[Cursor v3.4.20] Python environments extension not working

Support Help
, ,
1

I am trying to use the Python environments extension (ms-python.vscode-python-envs) with conda. The plugin tries to load the environments but does not load anything. I have tried several related workarounds without success:

I am using Cursor in Linux Mint, via an AppImage. This is my Cursor installation configuration:

Version: 3.4.20
VSCode Version: 1.105.1

OS: Linux x64 6.17.0-29-generic

From the environments log output, it seems that the environments are actually being detected:

I would appreciate any help- Thanks!

Hey @calegria!

Thanks for the report.

Is this working in VSCode? I’m asking because the right home for this issue may be on GitHub - microsoft/vscode-python-environments: VS Code extension for Python environment and package management · GitHub

Additionally, this appears to be an older version of the extension. The latest version is v1.30.0! Could you check which version you have installed?

Hi @Colin,

First of all, thanks for the answer!

Is this working in VSCode? …

I actually have not test it on VSCode. Will try and let you know.

Additionally, this appears to be an older version of the extension. The latest version is v1.130.0 !
Could you check which version you have installed?

Good catch! I actually installed the latest version showing up in the Extensions Marketplace at Cursor, which is v1.10.0. Will try to install v1.13.0, hopefully it solves the problem.

I feel like I’m going crazy – when I checked the Cursor marketplace yesterday I’m sure I saw v1.30! But today I only see v1.10.

I gave it a try, and it looks like Cursor isn’t compatible with the latest version, and the maintainers are only interested in keeping compatibility with VSCode. :confused:

Hi again @Colin,

I can confirm that the latest Python Environments extension (v1.30.0) works correctly in VSCode (v1.120.0).

However, I cannot find a way to install a newer version of the extension on Cursor, so I cannot test if upgrading will solve the issue. Is there a way to setup another repository for extensions?

There is a weird thing happening. When the extensions is first listed on the extensions window, the version is 1.30.0:

But then, after the extension is installed, the installed version is v.10.0!!

I have tried with different versions of the extension without success. Actually, extension v1.14.0 is the only one compatible with the VSCode version in which the current Cursor version is based on.
