Question

How to fix this error:

Error: Dependencies lock file is not found in /path/to/project. Supported file patterns: package-lock.json,yarn.lock

in actions/setup-node@v2 GitHub Action?

Answer

This error occurs because by default, this job searches for package-lock.json in the root of the repository for caching. We need to explicitly specify the location of our package-lock.json

             - name: Setup Node.js
               uses: actions/setup-node@v2
               with:
                   node-version: 16.14.0
                   cache: "npm"
+                  # The action defaults to search for the dependency file
+                  # (package-lock.json or yarn.lock) in the repository root, and uses
+                  # its hash as a part of the cache key.
+                  # https://github.com/actions/setup-node#caching-packages-dependencies
+                  cache-dependency-path: "./blog/package-lock.json"
