- name: Read required pnpm version from the action's package.json
id: pnpm-version
shell: bash
# `pnpm/action-setup`'s `package_json_file` input has the same resolution quirk as
# `actions/setup-node`'s `node-version-file`: absolute paths derived from `github.action_path`
# get concatenated with `$GITHUB_WORKSPACE` and the file is not found, at which point the
# action silently falls back to the caller's package.json (which does not declare a
# `packageManager` field) and fails with "No pnpm version is specified". Read the value here
# and pass it as a literal `version` instead. Node is on PATH because setup-node just ran.
