overrides + aliases + catalogs together?

[aaronadamsCA]

I was thinking I could do this, but it doesn't work:

catalog:
  rolldown-vite: 7.1.6

overrides:
  vite: 'npm:rolldown-vite@catalog:'

 ERR_PNPM_SPEC_NOT_SUPPORTED_BY_ANY_RESOLVER  vite@npm:rolldown-vite@catalog: isn't supported by any available resolver.

Is this a bug, a feature request, or just a bad idea?

I reproduced this on current pnpm (10.33.0), and the behavior matches the error you pasted:

catalog:
  rolldown-vite: 7.1.6
overrides:
  vite: "npm:rolldown-vite@catalog:"

with a dependency on vite: "catalog:" fails with:

ERR_PNPM_SPEC_NOT_SUPPORTED_BY_ANY_RESOLVER
"vite@npm:rolldown-vite@catalog:" isn't supported by any available resolver

So this is definitely not just a YAML typo or local setup problem.

My practical read is:

• catalog: works as its own specifier form
• npm: aliasing works as its own specifier form
• nesting catalog: inside an npm: alias string is not currently supported

So I would treat this as "not supported today" rather than "you're using it wrong in an otherwise supported way".

Whether that should become a feature is a separate question, but the current behavior looks much more like a feature gap / unsupported composition than a simple user mistake.
