I had an issue where pnpm was installed with corepack, but I would have a version mismatch when comparing the package manager in the package.json and the pnpm version in the terminal.

I created an issue with corepack: nodejs/corepack#659

After some debugging, we determined that I had 2 versions of pnpm installed.
One via corepack, and another via globally from npm.

See here as reference: nodejs/corepack#659 (comment)

I was then suggested to maybe add documentation to warn against this odd behaviour here: nodejs/corepack#659 (comment)

I am considering adding some information regarding this here: https://github.com/pnpm/pnpm.io/blob/main/docs/installation.md
on line 97.

:::warning

Having multiple package manager versions installed can cause an incorrect version of a package manager being used, regardless of the version that is specified in the package.json.

To verify there are not multiple version installed, see this [corepack issue 659](https://github.com/nodejs/corepack/issues/659#issuecomment-2658982866).
