Error "Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat)"

Question

I've installed Python 3.5 and while running

pip install mysql-python

it gives me the following error

error: Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat)

I have added the following lines to my Path

C:\Program Files\Python 3.5\Scripts\;
C:\Program Files\Python 3.5\;

C:\Windows\System32;
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC;
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC

I have a 64-bit Windows 7 setup on my PC.

What could be the solution for mitigating this error and installing the modules correctly via pip.

make sure to upgrade setuptools: `pip install --upgrade setuptools` see https://wiki.python.org/moin/WindowsCompilers — 3pitt, May 29 '18 at 18:35
Use this link to download [Visual C++ 2015 Build Tools](http://go.microsoft.com/fwlink/?LinkId=691126&fixForIE=.exe.). It will install Visual C++ 14.0 without installing Visual Studio. After the installation completes, retry pip install and you won't get the error again. — Lalit Kumar B, Aug 29 '18 at 08:42

Your path only lists Visual Studio 11 and 12, it wants 14, which is Visual Studio 2015. If you install that, and remember to tick the box for Languages → C++ then it should work.

On my Python 3.5 install, the error message was a little more useful, and included the URL to get it from:

error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

New working link.

As suggested by Fire, you may also need to upgrade setuptools package for the error to disappear:

pip install --upgrade setuptools

Binary install it the simple way!

Use the binary-only option for pip. For example, for mysqlclient:

pip install --only-binary :all: mysqlclient

Many packages don't create a build for every single release which forces your pip to build from source. If you're happy to use the latest pre-compiled binary version, use --only-binary :all: to allow pip to use an older binary version.

To solve any of the following errors:

Failed building wheel for misaka
Failed to build misaka
Microsoft Visual C++ 14.0 is required
Unable to find vcvarsall.bat

The solution is:

Go to Build Tools for Visual Studio 2017
Select free download under Visual Studio Community 2017. This will download the installer. Run the installer.
Select what you need under workload tab:

a. Under Windows, there are three choices. Only check Desktop development with C++.

b. Under Web & Cloud, there are seven choices. Only check Python development (I believe this is optional, but I have done it).
In cmd, type pip3 install misaka.

Note if you already installed Visual Studio then when you run the installer, you can modify yours (click modify button under Visual Studio Community 2017) and do steps 3 and 4.

Final note: If you don't want to install all modules, having the three below (or a newer version of the VC++ 2017) would be sufficient. (You can also install the Visual Studio Build Tools with only these options, so you don’t need to install Visual Studio Community Edition itself) => This minimal install is already a 4.5 GB, so saving off anything is helpful

As the other responses point out, one solution is to install Visual Studio 2015. However, it takes a few GBs of disk space.

One way around is to install precompiled binaries. The webpage Unofficial Windows Binaries for Python Extension Packages (mirror) contains precompiled binaries for many Python packages. After downloading the package of interest to you, you can install it using pip install, e.g. pip install mysqlclient‑1.3.10‑cp35‑cp35m‑win_amd64.whl.

Thanks. I believe `pip wheel` creates a wheel archive; and, `pip install` actually installs the specified wheel file. See https://pip.pypa.io/en/stable/reference/pip_wheel. Btw, this approach worked for me in installing `hmmlearn` package via `hmmlearn-0.2.1-cp36-cp36m-win_amd64.whl` wheel. – Oleg Melnikov Sep 14 '17 at 18:29

This is best solution here. Rather than going for monolithic visual studio, i opted this. If u need any package u can also search it on 'https://pypi.org/'. Just remember to append wheel with name. e.g 'python-Levenshtein wheels' – Manjeet Mar 02 '19 at 15:48

Well, good as a quick solution but if you later want to install something which doesn't have a precompiled binary, you will anyway have to go through all of this again. It's usually a better idea to hit at the root of the cause than just delaying it. +1 otherwise. – Fr0zenFyr Mar 12 '20 at 05:17

I had the exact issue while trying to install the Scrapy web scraping Python framework on my Windows 10 machine. I figured out the solution this way:

Download the latest (the last one) wheel file from this link: wheel file for twisted package
I'd recommend saving that wheel file in the directory where you've installed Python, i.e., somewhere on the local disk C:
Then visit the folder where the wheel file exists and run pip install <*wheel file's name*>
Finally, run the command pip install Scrapy again and you're good to use Scrapy or any other tool which required you to download a massive Windows C++ Package/SDK.

Disclaimer: This solution worked for me while trying to install Scrapy, but I can't guarantee the same happening while installing other software, packages, etc.

Do not use the latest twisted, use that one which match your python version i.e. for python3.6 use twisted with cp36 – Sojtin Mar 09 '18 at 16:34

I had this exact issue while trying to install `mayavi`.

I also had the common error: Microsoft Visual C++ 14.0 is required when pip installing a library.

After looking across many web pages and the solutions to this question, with none of them working, I figured out these steps (most taken from previous solutions) allowed this to work.

Go to Build Tools for Visual Studio 2017 and install Build Tools for Visual Studio 2017. Which is under All downloads (scroll down) → Tools for Visual Studio 2017
- If you have already installed this, skip to 2.
Select the C++ components you require (I didn't know which I required, so I installed many of them).
- If you have already installed Build Tools for Visual Studio 2017 then open the application Visual Studio Installer then go to Visual Studio Build Tools 2017 → Modify → Individual Components and selected the required components.
- From other answers, important components appear to be: C++/CLI support, VC++ 2017 version <...> latest, Visual C++ 2017 Redistributable Update, Visual C++ tools for CMake, Windows 10 SDK <...> for Desktop C++, Visual C++ Build Tools core features, Visual Studio C++ core features.
Install/Modify these components for Visual Studio Build Tools 2017.
This is the important step. Open the application Visual Studio Installer then go to Visual Studio Build Tools → Launch. Which will open a CMD window at the correct location for Microsoft Visual Studio\YYYY\BuildTools.
Now enter python -m pip install --upgrade setuptools within this CMD window.
Finally, in this same CMD window, pip install your Python library: pip install -U <library>.

If you get errors about unresolved symbols, make sure you opened the right command prompt for your environment. If you need the 64 bit developer tools you might have to open the command prompt from the windows start menu. — Dawied, Jun 30 '23 at 15:53

Use this link to download and install Visual C++ 2015 Build Tools. It will automatically download visualcppbuildtools_full.exe and install Visual C++ 14.0 without actually installing Visual Studio.

After the installation completes, retry pip install and you won't get the error again.

I have tested it on the following platforms and versions:

Python 3.6 on Windows 7 64-bit
Python 3.8 on Windows 10 64-bit

Use this and save time

pipwin is like pip, but it installs precompiled Windows binaries provided by Christoph Gohlke. Saves you a lot of time googling and downloading.

And in this case pipwin will solve the problem

To expand on the answers by ocean800, davidsheldon and user3661384:

You should now no longer use Visual Studio Tools 2015 since a newer version is available. As indicated by the Python documentation, you should be using Visual Studio Tools 2017 instead.

Visual C++ Build Tools 2015 was upgraded by Microsoft to Build Tools for Visual Studio 2017.

Download it from here.

You will also require setuptools. If you don't have setup tools, run:

pip install setuptools

Or if you already have it, be sure to upgrade it.

pip install setuptools --upgrade

For the Python documentation link above you will see that setuptools version must be at least 34.4.0 for Visual Studio Tools to work.

It's rather sad that Python needs to use another language platform's compiler to do its grunt work. Why did the python team not build their own compiler with just the bare bones of what is needed. – Andrew S Aug 15 '18 at 20:02
@AndrewS Yes it's sad but nessesary. Developing an efficient C compiler is no easy feat (like developing a new language). Especially cross platform (Windows insits on it's own non-standard system), so it is really impossible to expect that. C++ is even worse because it is much more complex (even during the develpment of the MS compiler for C++ there were massive problems getting support for all the syntax; hence the stdafx.h header to include the nessesary features). Doing this would mean using HUGE amounts of development time to reinvent the wheel. – Xantium Aug 15 '18 at 21:38
@AndrewS as well as almost double the development time to even maintain both projects ultimately slowing down each release of Python itself. Building off the already existing MS compiler is much easier (as they do not need to develop it). – Xantium Aug 15 '18 at 21:48

I had exactly the same issue and solved it by installing mysql-connector-python with:

pip install mysql-connector-python

I am on Python 3.7 and Windows 10 and installing Microsoft Build Tools for Visual Studio 2017 (as described here) did not solve my problem that was identical to yours.

Just go to https://www.lfd.uci.edu/~gohlke/pythonlibs/ find your suitable package (whl file). Download it. Go to the download folder in cmd or typing 'cmd' on the address bar of the folder. Run the command :

pip install mysqlclient-1.4.6-cp38-cp38-win32.whl

(Type the file name correctly. I have given an example only). Your problem will be solved without installing build toll cpp of 6GB size.

To add on top of Sushant Chaudhary's answer:

In my case, I got another error regarding lxml as below:

copying src\lxml\isoschematron\resources\xsl\iso-schematron-xslt1\readme.txt -> build\lib.win-amd64-3.7\lxml\isoschematron\resources\xsl\iso-schematron-xslt1

error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

I had to install lxml‑4.2.3‑cp37‑cp37m‑win_amd64.whl the same way as in the answer of Sushant Chaudhary to successfully complete installation of Scrapy.

Download lxml‑4.2.3‑cp37‑cp37m‑win_amd64.whl from Lxml
put it in folder where Python is installed
install it using pip install <file-name>

Now you can run pip install scrapy.

I just had the same issue while using the latest Python 3.6. With Windows OS 10 Home Edition and a 64-bit operating system.

Steps to solve this issue:

Uninstall any versions of Visual Studio you have had, through Control Panel
Install Visual Studio 2015 and chose the default option that will install Visual C++ 14.0 on its own
You can use PyCharm for installing Scrapy: Menu Project → Project Interpreter → + (install Scrapy)
Check Scrapy in the REPL and PyCharm by import. You should not see any errors.

I had a similar situation installing pymssql.

pip was trying to build the package, because there were no official wheels for Python 3.6 and Windows.

I solved it by downloading an unofficial wheel from Unofficial Windows Binaries for Python Extension Packages.

Specifically for your case: MySQL-python

None of the solutions here and elsewhere worked for me. It turns out an incompatible 32-bit version of mysqlclient is being installed on my 64-bit Windows 10 OS because I'm using a 32-bit version of Python.

I had to uninstall my current Python 3.7 32 bit, and reinstalled Python 3.7 64 bit and everything is working fine now.

I had the same exact issue on my windows 10 python version 3.8. In my case, I needed to install mysqlclient were the error occurred Microsoft Visual C++ 14.0 is required. Because installing visual studio and it's packages could be a tedious process, Here's what I did:

step 1 - Go to unofficial python binaries from any browser and open its website.

step 2 - press ctrl+F and type whatever you want. In my case it was mysqlclient.

step 3 - Go into it and choose according to your python version and windows system. In my case it was mysqlclient‑1.4.6‑cp38‑cp38‑win32.whl and download it.

step 4 - open command prompt and specify the path where you downloaded your file. In my case it was C:\Users\user\Downloads

step 5 - type pip install .\mysqlclient‑1.4.6‑cp38‑cp38‑win32.whl and press enter.

Thus it was installed successfully, after which I went my project terminal re-entered the required command. This solved my problem

Note that, while working on the project in pycharm, I also tried installing mysql-client from the project interpreter. But mysql-client and mysqlclient are different things. I have no idea why and it did not work.

I was facing the same problem. The following worked for me:

Download the unofficial binaries file from Christoph Gohlke installers site as per the Python version installed on your system.

Navigate to the folder where you have installed the file and run

pip install filename

For me python_ldap‑3.0.0‑cp35‑cp35m‑win_amd64.whl worked as my machine is 64 bit and Python version is 3.5.

This successfully installed python-ldap on my Windows machine. You can try the same for mysql-python.

If Visual Studio is NOT your thing, and instead you are using VS Code, then this link will guide you thru the installer to get C++ running on your Windows.

You only needs to complete the Pre-Requisites part. https://code.visualstudio.com/docs/cpp/config-msvc/#_prerequisites

This is similar with other answers, but this link will probably age better than some of the responses here.

PS: don't forget to run pip install --upgrade setuptools

Oops! Looks like they don't have Windows wheels on PyPI.

In the meantime, installing from source probably works or try downloading MSVC++ 14 as suggested in the error message and by others on this page.

Christoph's site also has unofficial Windows binaries for Python extension packages (.whl files).

Follow the steps mentioned in the following links to install binaries:

Also check:

I had the same issue while installing mysqlclient for the Django project.

In my case, it's the system architecture mismatch causing the issue. I have Windows 7 64bit version on my system. But, I had installed Python 3.7.2 32 bit version by mistake.

So, I re-installed Python interpreter (64bit) and ran the command

pip install mysqlclient

I hope this would work with other Python packages as well.

TLDR run vcvars64.bat

After endlessly searching through similar questions with none of the solutions working. -Adding endless folders to my path and removing them. uninstalling and reinstalling visual studio commmunity and build tools. and step by step attempting to debug I finally found a solution that worked for me.

(background notes if anyone is in a similar situation) I recently reset my main computer and after reinstalling the newest version of python (Python3.9) libraries I used to install with no troubles (main example pip install opencv-python) gave

cl
    is not a full path and was not found in the PATH.

after adding cl to the path from C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.27.29110\bin\Hostx64\x64

and several different windows kits one at a time getting the following.

The C compiler

"C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.27.29110/bin/Hostx64/x64/cl.exe"

is not able to compile a simple test program.

with various link errors or " Run Build Command(s):jom /nologo cmTC_7c75e\fast && The system cannot find the file specified"

upgrading setuptools and wheel from both a regular command line and an admin one did nothing as well as trying to manually download a wheel or trying to install with --only-binary :all:

Finally the end result that worked for me was running the correct vcvars.bat for my python installation namely running "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat" once (not vcvarsall or vcvars32) (because my python installed was 64 bit) and then running the regular command pip install opencv-python worked.

If you have already installed Visual Studio Build Tools (as in other comments), and upgraded setuptools but it still doesn't work:

Make sure to run pip under x86 or x64 Native Tools Command Prompt.

It can be found under VS folder in Windows start menu. The default command line prompt may NOT provide Pip the path to the VS build tool, as is in my case.
