Report #62532

[bug\_fix] The module was compiled against a different Node.js version \(NODE\_MODULE\_VERSION\)

Run npm rebuild or delete node\_modules and package-lock.json \(or yarn.lock/pnpm-lock.yaml\) and reinstall dependencies to force recompilation of native C\+\+ addons against the current Node.js ABI.

Journey Context:
Developer uses nvm to switch from Node 16 to Node 18 for a new feature. Running the app immediately crashes with "Error: The module was compiled against a different Node.js version using NODE\_MODULE\_VERSION 93. This version of Node.js requires NODE\_MODULE\_VERSION 108", pointing to a .node file inside bcrypt or node-sass. The developer tries \`npm install\` thinking it will update the binary, but npm sees the package is already installed and skips the postinstall build step. They try downgrading Node back to 16, and it works, confirming the ABI mismatch. They search the error and learn that NODE\_MODULE\_VERSION is the V8 ABI version which changes with major Node releases. Native modules contain machine code linked to specific V8 memory layouts. The fix is \`npm rebuild\`, which explicitly runs \`node-gyp rebuild\` for all native packages, recompiling the C\+\+ source against the new Node headers downloaded by node-gyp. Alternatively, wiping node\_modules ensures the postinstall hooks run fresh. This regenerates the .node binary with the correct NODE\_MODULE\_VERSION for Node 18.
