GitHub actions/setup-node README pnpm cache pnpm/action-setup order package manager must be installed before setup-node cache

💡 Result:

Yes, the order is critical when using actions/setup-node to cache pnpm dependencies. You must install pnpm before the actions/setup-node step [1][2]. This is because actions/setup-node attempts to resolve the location of the pnpm store by executing pnpm store path during its setup process [2]. If pnpm is not already installed and available in the system PATH when actions/setup-node runs, the step will fail with an error such as "Unable to locate executable file: pnpm" [1][3][2]. Recommended Configuration: 1. Install pnpm first using pnpm/action-setup (or pnpm/setup for newer versions) [2][4]. 2. Run actions/setup-node second, with cache: 'pnpm' enabled [5][2]. Example: - uses: pnpm/action-setup@v4 - uses: actions/setup-node@v4 with: node-version: 22 cache: 'pnpm' Modern Alternative: For projects using pnpm v11+, it is now recommended to use the pnpm/setup action instead [4]. This action can install both pnpm and a specified Node.js runtime in a single step, while also handling dependency caching natively [4][6]. This often eliminates the need for actions/setup-node entirely [4]. - uses: pnpm/setup@v1 with: version: 11 runtime: node@22 cache: true

Citations:

Install pnpm before enabling the pnpm cache.

actions/setup-node@v4 runs pnpm store path for cache: pnpm. Move pnpm/action-setup@v4 before actions/setup-node@v4.

In @.github/workflows/pages.yml around lines 28 - 34, Reorder the workflow steps
so pnpm/action-setup@v4 runs before the Setup Node step using
actions/setup-node@v4 with cache: pnpm, ensuring pnpm is available when
setup-node resolves the cache store path.
