Thanks for reporting a bug you have found in Cursor!
Please add the following info to help us diagnose your issue:

:white_check_mark: Check the forum to ensure the issue hasn’t been reported already
:lady_beetle: Provide a clear description of the bug
:arrows_counterclockwise: Explain how to reproduce the bug (if known)
:camera: Attach screenshots or recordings (e.g., .jpg, .png, .mp4).
:computer: Tell us your operating system and your Cursor version (e.g., Windows, 0.x.x).
:no_entry_sign: Tell us if the issue stops you from using Cursor.

As soon as I updated to Cursor 0.46, I started getting an error when trying to activate my Conda environment. I suspect this is due to PYTHONPATH conflicts. I unset both PYTHONPATH and PYTHONHOME, and that allowed the environment to activate. However, a new problem arose: Cursor doesn’t recognize my installed packages, even though I’ve selected the correct interpreter (the one where the packages are installed). Please see the attached images. This is quite annoying because I can’t jump to the module definitions directly.

To rollback i had to delete my cursor settings completely with

rm -rf ~/.cursor ~/.config/Cursor/

and get an “old” 0.45.11 appimage from GitHub - oslook/cursor-ai-downloads: all cursor ai version download links, and some older versions offer a better user experience
