"error: Microsoft Visual C++ 9.0 is required. Get it from http://aka.ms/vcpyt hon27" — PrasadK, Apr 28 '18 at 20:05
I've downloaded and installed Microsoft Visual C++ 9.0, but still no luck @PrasadK — S. Backlayn, Apr 28 '18 at 20:27
You mean it is still tells you to install Visual C++ 9.0 even after you installed it? Or does it print a different error message now? — Kubuntuer82, Apr 28 '18 at 23:52
Nope, same error but when I go into my programes, I see its installed @Kubuntuer82 — S. Backlayn, Apr 29 '18 at 11:41
And could you also show the output of `echo %VCINSTALLDIR% ` ? — Kubuntuer82, Apr 29 '18 at 14:55
Please also consider [this](https://stackoverflow.com/a/41843310/6854564) answer. Please follow the suggested procedure and let us know whether it fixes the issues. — Kubuntuer82, Apr 29 '18 at 14:57
But knowing the output of `echo %VCINSTALLDIR%` can still be important anyway — Kubuntuer82, Apr 29 '18 at 23:43
I dont get any output I just stays at `%VS90COMNTOOLS%` but I already found a solution, so thanks for helping! — S. Backlayn, May 01 '18 at 09:13

The solution was simple

just

    pip uninstall pycrypto
    pip install pycryptodome

And every should just work fine, it worked for me!

This is a _workaround_ rather than a solution, but it is still useful, because according to [this post](https://github.com/dlitz/pycrypto/issues/238) on the "Issues" section of the `pycrypto` official repository, it seems the package has not been maintained at all in the last years. And their recommendation is to install `pycryptodome` instead, since it still creates a `Crypto` package with the same namespace, so it is expected to work with source code based on the `pycrypto` libraries. – Kubuntuer82 May 02 '18 at 10:19
I have the same problem and tried ur solution and faced `WARNING: Skipping pycrypto as it is not installed.` – Farhang Amaji Jul 19 '21 at 18:04

In some cases it is a dependency issue. It can be solved as follows: for python2 run the following command: sudo apt-get install build-essential libssl-dev libffi-dev python-dev

For python3 run

sudo apt-get install build-essential libssl-dev libffi-dev python3-dev

This is correct answer! Lack of installed libraries is the reason for this error. Don't hurry to install alternatives. – ilyas Jumadurdyew Sep 13 '20 at 17:35

Can you please give the alternate command for windows? – Syed Md Ismail Mar 01 '21 at 15:12
This worked for me. In my case, the installation of SET failed at pycrypto build – Christopher C Okonkwo Apr 21 '23 at 09:32

I fixed same problem in linux running sudo apt-get install pythonX.X-dev before installing pycrypto. Replace pythonX.X with your python version e.g. sudo apt-get install python3.6-dev

After so many try with errors, now i have one solution for pycrypto and splunklib

Code of my Docker file that need to update :

FROM python:3.8-slim
RUN mkdir /app
WORKDIR /app
COPY requirements.txt /app
RUN pip install --no-cache-dir -r requirements.txt
RUN apt-get update && apt-get install -y --no-install-recommends gcc build- 
essential postgresql libpq-dev vim
COPY . /app
WORKDIR /app/api
EXPOSE 3000
CMD ["uvicorn", "api:app", "--host", "0.0.0.0",  "--port", "3000", "--reload"]

requirements.txt have

...

pycryptodome==3.14.1

splunk-sdk==1.6.19

splunklib==1.0.0

....

below error was showing for me when try to run above docker file code

            Building wheel for splunk-sdk (setup.py): started

            #9 80.50   Building wheel for splunk-sdk (setup.py): finished with status 'done'

            Running setup.py install for pycrypto: started

            #9 106.8   Running setup.py install for pycrypto: finished with status 'error'

            #9 106.9   error: subprocess-exited-with-error note: This error originates from a subprocess, and is likely not a problem with pip.

            #9 106.9 error: legacy-install-failure
            #9 106.9 Encountered error while trying to install package.
            #9 106.9 pycrypto

**Solution ** - Now i am updating docker file with below code

            FROM python:3.8-slim
            RUN mkdir /app
            WORKDIR /app
            COPY requirements.txt /app

            RUN apt-get install -y --no-install-recommends libssl-dev libffi-dev
            RUN pip install --no-cache-dir -r requirements.txt
            COPY . /app
            WORKDIR /app/api
            EXPOSE 3000

you can install pip install pycryptodomex as it is the only version that is now independent from the old PyCrypto library. Note: all modules are installed under the Cryptodome package e.g

from Cryptodome.Cipher import AES

you can read more from official docs here https://www.pycryptodome.org/src/introduction

There is no support whatsoever from the project. Specifically in windows. Pycrypto Issue Link.

For ubuntu these answers will work. But I guess for windows you should switch to pycryptodome as it installs the packages with the same crypto name as pycrypto,

Just make sure to copy Crypto folder to path where you have the script.py and complementary files.

You can check the path in IDLE shell

import Crypto as cr

print ("Pycryptodome version:"+ cr.__version__)
print (cr.__path__)
