Install in Cursor fails

[dickermoshe]

Installing ruff in Cursor results in the following:

What is stranger that this kicks off a task which makes a request once a second for pyright which is not available:

Thanks for the report! It's not exactly a direct comparison since I'm on Linux and only tried VS Code, but uninstalling and reinstalling works well for me. Could this be a Cursor-specific issue? Or maybe a temporary network problem?

[dickermoshe]

@ntBre Thanks for taking a look at this.

This issue applies to any of the VScode forks.

Some more context:
The pylance extension has a restrictive license. Only the Official VScode IDE is able to distribute it.
https://github.com/microsoft/vscode-python/blob/0b477a3baa6a64c3e0ebc9a58ee277b358bb93c1/build/license-header.txt#L5-L8
Microsoft does the same thing for some of the other extensions as well.

Cursor and the other VS Code forks therefore have to use alternatives.
https://open-vsx.org/extension/anysphere/pyright

This means that in order for ruff/ty to work on VScode forks, they must not depend on pylance.

Ah okay, I see, thanks. This is related to #479 and #636 then.

I'm a bit confused, though, because the cursor docs have a link to a Ruff extension. Is that what you're trying to install? There's also #846 (comment), where Micha mentions that he got the extension running in Cursor as expected.

I thought I looked for a Cursor issue. Sorry if this is a duplicate.

Ah okay, I see, thanks. This is related to #479 and #636 then.

I do not think so. I can install this extension using the VSIX file and it runs fine. It seems that it's an installation issue only.

I was able to install in vscode, so that may indicate that it is not an network issue.

[dickermoshe]

Very very odd.

I uninstalled the extension and reinstalled it using Cursor (as opposed to a VSIX file) and it worked.

Thank you so much. Sorry for all this trouble. Have an awesome Thursday.

I'm really really enjoying ruff/ty. Such a pleasure to use. You guys are the best. Keep it up.

No worries at all, thank you for the report, for the updates, and for the kind words! I'm glad it's working now :)

I have the same problem, not only with Ruff but also with Ty, possibly because I installed them earlier using the official scripts on the website. The extensions won't install. This didn't happen before the update.

have the same issue in Cursor - am only able to install via VSIX file. Same with the ty extension as well

Am on macOS on cursor version: 2.4.27 if that makes any difference

Solution! Download the .vsix extension file directly and import it directly into Cursor. This helped me.
