Usage Error: This project is configured to use <pkgmgr>

See original GitHub issue

One of the biggest problems I have today with Corepack is the Usage Error: This project is configured to use <pkgmgr>.

This happens when I run npm i -g vercel@latest in a project that is configured to use yarn or pnpm. This seems a little too strict because the global flag (-g) is not scoped to my current project.

Similarly, vercel dev will shell out to npm or npx and corepack being enabled could block it from working properly, even if the system has npm installed.

While I think the intention is good (catch accidental typos), I think this shouldn’t be the default behavior because it is too restrictive. Perhaps making this strict mode be opt-in would help Corepack go stable (see #104).

I would also like to be able to run things like yarn --version or npm --version in a situation where corepack is enabled. This early UsageError prevents me from doing that. While debugging @nathanhammond and I noticed that config.json contains an allowlist of commands that are passed through: https://github.com/nodejs/corepack/blob/312d9ea6f107ef05c7e8955538b9abd9f857f8a6/sources/main.ts#L46-L55

I’m not sure if my case is a good use case for this config, but may be a good place to start?

Or it could spawn a prompt: You are running a command the uses <pkgmng> in a directory configured to use <pkgmng>. Do you want to continue?.
