Peristent issues with Pylance

Bug Report

Hi,

it seems many users have had this problem, that the Pylance server doesn’t work in Cursor.

What do I do to fix this?

Best,

I am a new user and have been struggling with this. I have tried everything people have stated here and still get buggy behavior and have to jump through hoops. I have yet to get a response from any moderators. This is a bummer as cursor is pretty cool but the fact that they don’t support this or have docs on how to solve this problem is insane. Its jut not useable at this point.

The real issue comes down to Microsoft being exclusive. You can’t actually use Pylance outside of Microsoft as you see in your error message. My understanding is that Cursor has tried to do sneaky things to make it work but eventually it always breaks. This is just not sustainable. They are losing a TON of potential customers until they figure out a real solution. You just can’t barely half support one of the biggest coding languages in the world and have zero documentation explaining how to fix the problem. Hopefully enough people complain and it puts a fire under them because I think it really is an awesome product when you are not spending hours figuring out the mess. :stuck_out_tongue:

I would like to respond with a solution:

  1. Install basedpyright (documentation)
  2. follow the dialogue which says uninstall pyright and restart
  3. enjoy

Best,
Marius

Yeah this is the best you can do… but BasedPyright is not the same and I am not a fan of how it works. It also doesn’t do well with my job’s workspace setup for vscode so unfortunately I can’t really use cursor without jumping through some hoops.
