python - PyCharm doesn't recognise 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

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

File->Default Settings->Project Interpretor

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.

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.

Open File -> Settings -> Project Interpreter, pick "Show All..." (to edit the config) (1), pick your interpreter (2), and click "Show paths of selected interpreter" (3).

In that screen, manually add the "site-packages" directory of the virtual environment (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 3

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 4

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 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

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: [email protected]
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.

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

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 9

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 10

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 11

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 12

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 13

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 14

I got this issue when I created the project using Virtualenv.

Solution suggested by Neeraj Aggarwal worked for me. However, if you do not want to create a new project then the following can resolve the issue.

1. Close the project
2. Find the file <Your Project Folder>/venv/pyvenv.cfg
3. Open this file with any text editor
4. Set the include-system-site-packages = true
5. Save it
6. Open the project

Answer 15

In your pycharm terminal run pip/pip3 install package_name
