Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
“Cursor Pyright depends on the ms-python.python extension, which is not installed. Please install this extension.” error on both Mac & Linux, causing no go to definition, broken highlighting, etc
Fundamentally same issue as Cursor Pyright does not find ms-python.python, although commented workarounds have not helped
Steps to Reproduce
So far I have seen this on Mac & Linux under all conditions I’ve tried. Just install cursor and the core python extensions and restart (there is a brief window when they appear to work before restarting).
No amount of application, extension re-installation, settings.json fiddling has helped.
Expected Behavior
Python language features / intellisense work when first-party extensions are installed.
