PyCharm doesn't recognize installed module

Question

I'm having trouble with using 'requests' module on my Mac. I use python34 and I installed 'requests' module via pip. I can verify this via running installation again and it'll show me that module is already installed.

15:49:29|mymac [~]:pip install requests
Requirement already satisfied (use --upgrade to upgrade): requests in /opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages

Although I can import 'requests' module via interactive Python interpreter, trying to execute 'import requests' in PyCharm yields error 'No module named requests'. I checked my PyCharm Python interpreter settings and (I believe) it's set to same python34 as used in my environment. However, I can't see 'requests' module listed in PyCharm either.

It's obvious that I'm missing something here. Can you guys advise where should I look or what should I fix in order to get this module working? I was living under impression that when I install module via pip in my environment, PyCharm will detect these changes. However, it seems something is broken on my side ...

Answer 1

In my case, using a pre-existing virtualenv did not work in the editor - all modules were marked as unresolved reference (running naturally works, as this is outside of the editor's config, just running an external process (not so easy for debugging)).
Turns out PyCharm did not add the site-packages directory... the fix is to manually add it.

On Pycharm professional 2022.3

Open File -> Settings -> Python Interpreter, open the drop-down and pick "Show All..." (to edit the config) (1), right click your interpreter (2), click "Show Interpreter Paths" (3).

In that screen, manually add the "site-packages" directory of the virtual environment [looks like .../venv/lib/python3.8/site-packages (4) (I've added the "Lib" also, for a good measure); once done and saved, they will turn up in the interpreter paths.

The other thing that won't hurt to do is select "Associate this virtual environment with the current project", in the interpreter's edit box.

Answer 2

If you are using PyCharms CE (Community Edition), then click on:

File->Default Settings->Project Interpreter

See the + sign at the bottom, click on it. It will open another dialog with a host of modules available. Select your package (e.g. requests) and PyCharm will do the rest.

Answer 3

This issue arises when the package you're using was installed outside of the environment (Anaconda or virtualenv, for example). In order to have PyCharm recognize packages installed outside of your particular environment, execute the following steps:

Go to

Preferences -> Project -> Project Interpreter -> 3 dots -> Show All -> Select relevant interpreter -> click on tree icon Show paths for the selected interpreter

Now check what paths are available and add the path that points to the package installation directory outside of your environment to the interpreter paths.

To find a package location use:

$ pip show gym
Name: gym
Version: 0.13.0
Summary: The OpenAI Gym: A toolkit for developing and comparing your reinforcement learning agents.
Home-page: https://github.com/openai/gym
Author: OpenAI
Author-email: gym@openai.com
License: UNKNOWN
Location: /usr/local/lib/python3.7/site-packages
...

Add the path specified under Location to the interpreter paths, here

/usr/local/lib/python3.7/site-packages

Then, let indexing finish and perhaps additionally reopen your project.

Answer 4

Open python console of your pyCharm. Click on Rerun. It will say something like following on the very first line

/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 /Applications/PyCharm.app/Contents/helpers/pydev/pydevconsole.py 52631 52632

in this scenario pyCharm is using following interpretor

/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 

Now fire up console and run following command

sudo /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 -m pip install <name of the package>

This should install your package :)

Answer 5

Pycharm is unable to recognize installed local modules, since python interpreter selected is wrong. It should be the one, where your pip packages are installed i.e. virtual environment.

I had installed packages via pip in Windows. In Pycharm, they were neither detected nor any other Python interpreter was being shown (only python 3.6 is installed on my system).

I restarted the IDE. Now I was able to see python interpreter created in my virtual environment. Select that python interpreter and all your packages will be shown and detected. Enjoy!

Answer 6

Using dual python 2.7 and 3.4 with 2.7 as default, I've always used pip3 to install modules for the 3.4 interpreter, and pip to install modules for the 2.7 interpreter.

Try this:

pip3 install requests

Answer 7

This is because you have not selected two options while creating your project:- ** inherit global site packages ** make available to all projects Now you need to create a new project and don't forget to tick these two options while selecting project interpreter.

Answer 8

The solution is easy (PyCharm 2021.2.3 Community Edition). I'm on Windows but the user interface should be the same. In the project tree, open External libraries > Python interpreter > venv > pyvenv.cfg. Then change:

include-system-site-packages = false

to:

include-system-site-packages = true

Before going further, I want to point out how to configure a Python interpreter in PyCharm:
[SO]: How to install Python using the "embeddable zip file" (@CristiFati's answer). Although the question is for Win, and has some particularities, configuring PyCharm is generic enough and should apply to any situation (with minor changes).

There are multiple possible reasons for this behavior.

1. Python instance mismatch

• Happens when there are multiple Python instances (installed, VEnvs, Conda, custom built, ...) on a machine. Users think they're using one particular instance (with a set of properties (installed packages)), but in fact they are using another (with different properties), hence the confusion. It's harder to figure out things when the 2 instances have the same version (and somehow similar locations)

• Happens mostly due to environmental configuration (whichever path comes 1^st in ${PATH}, aliases (on Nix), ...)

• It's not PyCharm specific (meaning that it's more generic, also happens outside it), but a typical PyCharm related example is different console interpreter and project interpreter, leading to confusion

• The fix is to specify full paths (and pay attention to them) when using tools like Python, PIP, .... Check [SO]: How to install a package for a specific Python version on Windows 10? (@CristiFati's answer) for more details

• This is precisely the reason why this question exists. There are 2 Python versions involved:

  1. Project interpreter: /Library/Frameworks/Python.framework/Versions/3.4

  2. Interpreter having the Requests module: /opt/local/Library/Frameworks/Python.framework/Versions/3.4

  well, assuming the 2 paths are not somehow related (SymLinked), but in latest OSX versions that I had the chance to check (Catalina, Big Sur, Monterey) this doesn't happen (by default)

When dealing with this kind of error, it always helps (most likely) displaying the following information (in a script or interpreter console):

import os
import sys


print("Executable:", sys.executable)
print("Version:", sys.version)
print("CWD:", os.getcwd())
print("UName:", getattr(os, "uname", lambda: None)())
for evn in ("PATH", "PYTHONHOME", "PYTHONPATH"):
    print("{:s}: {:}".format(evn, os.environ.get(evn)))
print("sys.path:", sys.path)

2. Python's module search mechanism misunderstanding

• According to [Python.Docs]: Modules - The Module Search Path:

  When a module named spam is imported, the interpreter first searches for a built-in module with that name. These module names are listed in sys.builtin_module_names. If not found, it then searches for a file named spam.py in a list of directories given by the variable sys.path. sys.path is initialized from these locations:

  • The directory containing the input script (or the current directory when no file is specified).

  • PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH).

  • The installation-dependent default (by convention including a site-packages directory, handled by the site module).

  A module might be located in the current dir, or its path might be added to ${PYTHONPATH}. That could trick users into making them believe that the module is actually installed in the current Python instance ('s site-packages). But, when running the current Python instance from a different dir (or with different ${PYTHONPATH}) the module would be missing, yielding lots of headaches

• A somewhat related scenario: [SO]: ModuleNotFoundError: No module named 'cryptography.hazmat'; 'cryptography' is not a package (@CristiFati's answer)

• For a fix, check [SO]: How PyCharm imports differently than system command prompt (Windows) (@CristiFati's answer)

3. A PyCharm bug

• Not very likely, but it could happen. An example (not related to this question): [SO]: PyCharm 2019.2 not showing Traceback on Exception (@CristiFati's answer)

• To fix, follow one of the options from the above URL

4. A glitch

• Not likely, but mentioning anyway. Due to some cause (e.g.: HW / SW failure), the system ended up in an inconsistent state, yielding all kinds of strange behaviors

• Possible fixes:

  • Restart PyCharm

  • Restart the machine

  • Recreate the project (remove the .idea dir from the project)

  • Reset PyCharm settings: from menu select File -> Manage IDE Settings -> Restore Default Settings.... Check [JetBrains]: Configuring PyCharm settings or [JetBrains.IntelliJ-Support]: Changing IDE default directories used for config, plugins, and caches storage for more details

  • Reinstall PyCharm

  Needless to say that the last 2 options should only be attempted as a last resort, and only by experts, as they might mess up other projects and not even fix the problem

Not directly related to the question, but posting:

• [SO]: Run / Debug a Django application's UnitTests from the mouse right click context menu in PyCharm Community Edition? (a PyCharm related investigation from a while ago)

• [SO]: ImportError: No module named win32com.client (@CristiFati's answer)

Answer 10

1. If you go to pycharm project interpreter -> clicked on one of the installed packages then hover -> you will see where pycharm is installing the packages. This is where you are supposed to have your package installed.

2. Now if you did sudo -H pip3 install <package> pip3 installs it to different directory which is /usr/local/lib/site-packages

since it is different directory from what pycharm knows hence your package is not showing in pycharm.

Solution: just install the package using pycharm by going to File->Settings->Project->Project Interpreter -> click on (+) and search the package you want to install and just click ok.

-> you will be prompted package successfully installed and you will see it pycharm.

Answer 11

If any one faces the same problem that he/she installs the python packages but the PyCharm IDE doesn't shows these packages then following the following steps:

1. Go to the project in the left side of the PyCharm IDE then
2. Click on the venv library then
3. Open the pyvenv.cfg file in any editor then
4. Change this piece of code (include-system-site-packages = flase) from false to true
5. Then save it and close it and also close then pycharm then
6. Open PyCharm again and your problem is solved. Thanks

Answer 12

This did my head in as well, and turns out, the only thing I needed to do is RESTART Pycharm. Sometimes after you've installed the pip, you can't load it into your project, even if the pip shows as installed in your Settings. Bummer.

Answer 13

For Anaconda:

Start Anaconda Navigator -> Enviroments -> "Your_Enviroment" -> Update Index -> Restart IDE.

Solved it for me.

Answer 14

After pip installing everything I needed. I went to the interpreter and re-pointed it back to where it was at already. My case: python3.6 in /anaconda3/bin/python using virtualenv...

Additionally, before I hit the plus "+" sign to install a new package. I had to deselect the conda icon to the right of it. Seems like it would be the opposite, but only then did it recognize the packages I had/needed via query.

Answer 15

In my case the packages were installed via setup.py + easy_install, and the they ends up in *.egg directories in site_package dir, which can be recognized by python but not pycharm.

I removed them all then reinstalled with pip install and it works after that, luckily the project I was working on came up with a requirements.txt file, so the command for it was:

pip install -r ./requirement.txt

Answer 16

I just ran into this issue in a brand new install/project, but I'm using the Python plugin for IntelliJ IDEA. It's essentially the same as PyCharm but the project settings are a little different. For me, the project was pointing to the right Python virtual environment but not even built-in modules were being recognized.

It turns out the SDK classpath was empty. I added paths for venv/lib/python3.8 and venv/lib/python3.8/site-packages and the issue was resolved. File->Project Structure and under Platform Settings, click SDKs, select your Python SDK, and make sure the class paths are there.

Answer 17

pip install --user discord

above command solves my problem, just use the "--user" flag

Answer 18

I fixed my particular issue by installing directly to the interpreter. Go to settings and hit the "+" below the in-use interpreter then search for the package and install. I believe I'm having the issue in the first place because I didn't set up with my interpreter correctly with my venv (not exactly sure, but this fixed it).

I was having issues with djangorestframework-simplejwt because it was the first package I hadn't installed to this interpreter from previous projects before starting the current one, but should work for any other package that isn't showing as imported. To reiterate though I think this is a workaround that doesn't solve the setup issue causing this.

Answer 19

If you are having issues with the underlying (i.e. pycharm's languge server) mark everything as root and create a new project. See details: https://stackoverflow.com/a/73418320/1601580 this seems to happy to me only when I install packages as in editable mode with pip (i.e. pip install -e . or conda develop).

Answer 20

--WINDOWS-- if using Pycharm GUI package installer works fine for installing packages for your virtual environment but you cannot do the same in the terminal,

this is because you did not setup virtual env in your terminal, instead, your terminal uses Power Shell which doesn't use your virtual env

there should be (venv) before you're command line as shown instead of (PS)

if you have (PS), this means your terminal is using Power Shell instead of cmd

to fix this, click on the down arrow and select the command prompt

select command prompt

now you will get (venv) and just type pip install #package name# and the package will be added to your virtual environment

Answer 21

I tried all the answers but non of them worked!

""IF YOU ARE LAZY!! Temporary Answer is : ""

you should consider finding the path PyCharm is really installing libraries via pip in terminal and add that to your project like in the next pictures!

1_ go to interpreter settings :

2_ click on "Show All" :

3_ find your current projects interpreter and click on show Paths for selected interpreter :

4_ Now try adding different paths that you think might pip be installing libraries to and it adds all the libraries from that path to your new project :

Answer 22

On windows I had to cd into the venv folder and then cd into the scripts folder, then pip install module started to work

cd venv
cd scripts
pip install module

Answer 23

instead of running pip install in the terminal -> local use terminal -> command prompt

see below image

pycharm_command_prompt_image

Answer 24

In your pycharm terminal run pip/pip3 install package_name
