Note that upgrading to v4.4.0 fixes the issue

Hey @greg0ire, can you reproduce the issue on https://psalm.dev ?

[greg0ire]

Nope, sorry little bot

[muglug]

I think this was fixed in the current release - do you still see it?

[weirdan]

@muglug Psalm 3.11.2@d470903722cfcbc1cd04744c5491d3e6d13ec3d9 (in the error message) is the current release as far as can tell.

[vasily-kartashov]

Try with --no-cache. Solved it for me.

[greg0ire]

It must have to do with cache because it works after a reboot.

[YetiCGN]

@greg0ire Then, I believe, you can close the ticket. 😉

[greg0ire]

I will let Matthew Brown decide on this, maybe there is something that needs to be fixed, like auto-cleaning the cache under some circumstances. Or maybe this will never happen again for some other reason and it can be closed, but since it happen to me and other people, I guess it could happen again to anyone.

[muglug]

@zerkms this fits the bill of an easy problem to fix – the cache should clear whenever there's a lockfile change, but it appears not to be

[weirdan]

However multiple lockfiles may need to be considered when Psalm is installed globally (with composer global require vimeo/psalm).
