In 2025, on MacOS, I needed to:

Go to Project settings;
In Platform Settings - SDKs, make sure proper Python SDK exists.
- I had to choose Homebrew Python instead of the stock /usr/local/bin/python;
In Platform Settings - Global Libraries, check that the SDK has a collection of paths in "Site Packages" list box. The stock Python SDK had it empty in my case.
In Project - SDK, check that the right SDK is selected.
In Project - Modules, check that your module has this SDK selected, and has interpreter library – (my problem was that the stock Python SDK didn't have it).
In Project - Facets, check that the right SDK is selected.

Perhaps some of these steps are redundant, but better safe than sorry.

resurrecting an old thread for 2022 - in my case I had to create a local python interpreter facet since i was using a remote one over SSH I'd get red squiggles even over import time even though it'd run on the remote system (A raspberry pi).

Some answers here work and say to make a facet but my case was different since i had one, just one that didn't work locally.

(solved my problem) File -> Project structures -> Modules -> Add (small plus sign) -> Import Module -> Add the path contains the files (e.g. src/mymodule) -> Create Module from existing sources -> Next -> next -> Finish. You should see a file with .iml in the directory where you cannot import; that should do the trick

Even my Intellisense in Pycharm was not working for modules like time Problem in my system was no Interpreter was selected Go to File --> Settings... (Ctrl+Alt+S) Open Project Interpreter

Project Interpreter In my case was selected. I selected the available python interpreter. If not available you can add a new interpreter.

I got it to work after I unchecked the following options in the Run/Debug Configurations for main.py

Add content roots to PYTHONPATH

Add source roots to PYTHONPATH

This is after I had invalidated the cache and restarted.

Few steps that helped me (some of them are mentioned above):

Open project structure by:

command + ; (mac users) OR right click on the project -> Open Module Settings

Facets -> + -> Python -> <your-project> -> OK
Modules -> Python -> <select python interpreter>
Project -> Project SDK -> <select relevant SDK>
SDKs -> <make sure it's the right one>

Click OK.

Open Run/Debug Configurations by: Run -> Edit Configurations

Python Interpreter -> <make sure it's the right one>

Click OK.

Another possible fix (solved my problem)

You might have configured the environment properly but for some reason it broke along the way. In this case go to:

file > project settings > modules

Deploy the list of SDKs and look for a red line with [invalid] at the end. If you find one, you have to recreate a python sdk.

It is likely that your previously working SDK is there too, but not red. Delete it.

Now you can click on the new button and add your favorite python virtualenv. And it should work now.

Have you set up a python interpreter facet?

Open Project Structure CTRL+ALT+SHIFT+S

Project settings -> Facets -> expand Python click on child -> Python Interpreter

Then:

Project settings -> Modules -> Expand module -> Python -> Dependencies -> select Python module SDK

This is how i solved my problem (i have imported the project and it was showing there only, newly created files were not showing those errors):

1) Command + alt + R (Control in case of windows

2) Debug window will appear, select your file and press right arrow (->) and choose Edit then press enter (Edit configuration setting window will appear)

3) Under configuration, at the bottom you can see the error (please select a module with a valid python sdk), So in Python Interpreter, check Use Specified Interpreter, then in drop down you select your Python version

(In case python is not there download python plugin for intelliJ using following link https://www.jetbrains.com/help/idea/2016.3/installing-updating-and-uninstalling-repository-plugins.html

4) Click on apply then close it.

Bingo it's done.

My problem was similar to @Toddarooski 's, except that the module I had, under the "Dependencies" tab, had no SDK listed. I right clicked on 'SDK', picked edit from the drop down menu, and selected my Python SDK. That did the trick.

Just create and add Python SDK

File -> Project Structure -> Project -> Project SDK -> new

and select the installation path of your Python interpreter (for example, C:\Python26 in windows and /usr/bin/python2.7 in Linux) as the home path.

Use a Requirements File (see link to JetBrains documentation)

In my case I needed arrow. So, I added

arrow==0.7.0

to my projects requirements.txt

Then Intellij prompted me to add the library the first time that I wrote import arrow in a Python script

If your Python SDK is properly configured and you are still facing the problem that builtins are not recognized, try this:

File -> Invalidate Caches/Restart

Here's what I had to do. (And I probably forgot an important aspect of my problem, which is that this wasn't set up as a Python project originally, but a Java project, with some python files in them.)

Project Settings -> Modules -> Plus button (add a module) -> Python

Then, click the "..." button next to Python Interpreter.

In the "Configure SDK" dialog that pops up, click the "+" button. Select "Python SDK", then select the default "Python" shortcut that appears in my finder dialog

Wait about 5 minutes. Read some productivity tips. :)

Click Ok

Wait for the system to rebuild some indexes.

Hooray! Code hinting is back for my modules!
