Support installing pnpm in another folder rather than fixed in GITHUB_WORKSPACE

[lucienshawls]

For a mono repo, it is possible that the package.json is in ./docs, but currently, pnpm/setup@v1 could only install pnpm in GITHUB_WORKSPACE, which brings errors.

Could it be possible to install pnpm in the directory where package-json-file is nested?

If the file package.json resides in ./docs directory, then the action template below should install the project just fine.

jobs:
  build:
    runs-on: ubuntu-latest
    defaults:
      run:
        working-directory: ./docs

    strategy:
      matrix:
        node-version: [22]

    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: setup Node and pnpm
        uses: pnpm/setup@v2
        with:
          runtime: node@${{ matrix.node-version }}
          package-json-file: './docs/package.json'
          install: false

      - name: Run pnpm install
        run: pnpm install

But yes, the package raises an error on pnpm install by its own and doesn't respect the package-json-file path. This is why i have a seperate step pnpm install which runs on a directory that i want.

Let me know if this workaround solves your issue.

Yes, that works.

But I was worried if the pnpm store cache could work as intended, since the cache step is in pnpm/setup, but the package installation step is not.
