Why is PyCharm Showing 'No Module Named Requests' Despite Installation?

Unresolved Requests Module in PyCharm

When working with the 'requests' module in PyCharm, you may encounter an error stating 'No module named requests'. This issue arises despite the module being installed via pip and verifiable through the Python interpreter.

The root cause of this problem lies in PyCharm's incorrect handling of site-packages directories. By default, PyCharm does not automatically add the site-packages directory to the Python interpreter's path. This results in PyCharm being unable to detect installed modules like 'requests'.

Solution:

To resolve this issue, you need to manually add the site-packages directory to PyCharm's Python interpreter path.

Steps for PyCharm Professional 2022.3:

1. Open "File" > "Settings" > "Python Interpreter".
2. Click on the drop-down arrow and select "Show All..." to edit the configuration.
3. Right-click on your interpreter and select "Show Interpreter Paths".
4. Manually add the "site-packages" directory to the interpreter paths. For example, if your virtual environment is located in "/venv", you would add "/venv/lib/python3.8/site-packages".
5. Click "OK" to save your changes.

Alternatively, you can also associate the virtual environment with your project by selecting "Associate this virtual environment with the current project" in the interpreter's edit box.
