Migrate slides to Alchemmist 0.3.0 - #23
Conversation
📝 WalkthroughWalkthroughThe PR migrates the project and Pages workflow from Yarn to pnpm, requires Node.js 24, updates Slidev and Playwright packages, and changes slide pagination, footer metadata, and centered-slide layouts. ChangesPresentation build update
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The deployment workflow enables pnpm caching before pnpm is installed, which can cause the build to fail before dependencies are installed. Merge should wait for that setup order to be corrected. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

actions/setup-node cache pnpm requires pnpm installed before setup-node official documentation
💡 Result:
Yes, the actions/setup-node action requires that pnpm be installed in the environment before the action executes if you intend to use the cache: 'pnpm' feature [1][2][3]. The actions/setup-node action does not install pnpm itself [2]. When you set cache: 'pnpm', the action attempts to interact with the pnpm executable to manage the cache [1][3]. If pnpm is not already present on the runner—which is often the case, as it is not pre-installed on standard GitHub-hosted runners—the action will fail or, in newer versions, log a warning and skip the caching process [2][4][5]. To correctly configure caching for pnpm dependencies, follow these steps: 1. Install pnpm first: Use a dedicated action such as pnpm/action-setup before your setup-node step [6][2]. 2. Configure setup-node: Specify cache: 'pnpm' in the actions/setup-node step [6][3]. Example workflow configuration: yaml steps: - uses: actions/checkout@v4 - uses: pnpm/action-setup@v3 with: version: 10 - uses: actions/setup-node@v4 with: node-version: '24' cache: 'pnpm' - run: pnpm install If you prefer not to install pnpm beforehand or encounter issues with automatic caching, you can disable the feature by setting package-manager-cache: false or omitting the cache input, then managing the cache manually using actions/cache [1][6][2].

🌐 Web query:
site:github.com/actions/setup-node pnpm cache pnpm installed before setup-node cache documentation
💡 Result:
When using the pnpm caching feature provided by the actions/setup-node GitHub Action, pnpm must be installed and available in the system PATH before the setup-node action executes [1][2][3]. This requirement exists because the action attempts to interact with pnpm to determine the correct cache path during its execution [1][3]. If pnpm is not yet installed when setup-node runs, the action may fail with an error such as "Unable to locate executable file: pnpm" [1][2]. Recommended configuration: To correctly implement pnpm caching, follow the official recommendation by using the pnpm/action-setup action before the actions/setup-node action in your workflow [4][3]. Example workflow structure: steps: - uses: actions/checkout@v7 - uses: pnpm/action-setup@v6 with: version: 10 - uses: actions/setup-node@v7 with: node-version: '24' cache: 'pnpm' - run: pnpm install Alternative approach: If you prefer to install pnpm after the setup-node action (or manage the installation differently), you must disable the automatic caching functionality within setup-node to prevent it from failing [2][3]. You can do this by setting the package-manager-cache input to false [5][2][3]: steps: - uses: actions/checkout@v7 - uses: actions/setup-node@v7 with: node-version: '24' package-manager-cache: false # Now install pnpm and perform manual caching if needed - run: npm i -g pnpm - run: pnpm install
