Invalid Python SDK in PyCharm

Since this morning, I'm no longer able to run projects in PyCharm.

When generating a new virtual environment, I get an "Invalid Python SDK" error. Cannot set up a python SDK at Python 3.11... The SDK seems invalid.

What I noticed: No matter what base interpreter I select (3.8, 3.9, 3.10) Pycharm always generates a Python 3.11 interpreter.

I did completely uninstall PyCharm, as well as all my python installations and reinstalled everything. I also went through the "Repair IDE" option in PyCharm. I also removed and recreated all virtual environments.

When I run "cmd" and type 'python' then python 3.10.1 opens without a problem.

This morning, I installed a new antivirus software that did some checks and deleted some "unnecessary files" - maybe it is related (antivirus software is uninstalled again).

I had the same problem on Linux. Solved it by invalidating caches as suggested here: https://stackoverflow.com/a/45099651/3990607

In pycharm click on File menu, then choose Invalidate caches..., tick all 4 boxes and then restart PyCharm. Solved the problem for me.

Dealt with the same issue despite using python and pycharm without issue for months. Recently kept giving me the error despite changing the PATH variable of my system and even manually pathing within pycharm. After hours of reinstalling pycharm, python and even jumping around versions with no success it turned out it was because my python directory had a space in it that it just randomly decided to break.

For anyone who has tried what seems like everything to no avail ensure that NO part of the path to your python directory contains spaces

Had the same issue just today. I was able to resolve it by uninstalling python 3.10.1 and then reinstalling it under directory "C:/Program Files" instead of the default directory where it goes.

There are many other fixes also suggested by people all over the internet such as:

  • Installing an older version of Pycharm i.e. 2021.2
  • Allowing the pycharmProjects folder in windows defender

But the change of installation directory is what worked for me.

Python 3.10 version installed through windows store didn't have any spaces in default directory names (as my username doesn't have a space within itself). I id invalidated caches through the file menu. However, patapouf_ai had suggested doing it for Linux. The problem was resolved for me after installing and then reinstalling it through windows' remove and store, and it seems it's been caused by changing windows' user account control level to "never notify." The other possibility is that somehow python 3.10 has stopped functioning without a good reason and lost recognition by windows (not updated or modified by any means).

using IDLE

import sys

print(sys.executable)

#output is a path to where the interpreter is, copy path

PyCharm / file / settings / Project / Python Interpreter / show all / paste path
