If there's anything else accompanying the error, do you mind filing an issue? I've been using the ty extension with Cursor for weeks and am having trouble reproducing right now.
That's the full error. It shows up in a dialog box when I press the install button. I'm on macOS, connected with the Anysphere Remote SSH extension to a Linux machine.
If I choose "install previous version" I am able to install the pre-release version from 12 hours ago without issue. Then on the extension page I get a button labeled "Switch to Release Version" and when I press it I get an error that says "Can't install release version of 'ty' extension because it has no release version." Filed a GitHub issue with these details.
In the meantime, the previous version appears to be working well! I like that it worked without any configuration. The Pyrefly extension needed a config tweak to work.
https://forum.cursor.com/t/newly-published-extensions-appear... suggests that there's some kind of delayed daily update for new VSCode extension versions to become available to Cursor? It seems likely that's what is happening here, since ty-vscode 0.0.2 was only published an hour or two ago.
