Report #10500

[bug\_fix] Error: Module did not self-register / The module was compiled against a different Node.js version \(ABI mismatch\)

Root cause: Native Node.js addons \(binary \`.node\` files\) are compiled against a specific Node.js ABI \(Application Binary Interface\) version \(represented by \`NODE\_MODULE\_VERSION\`\). When you upgrade Node.js \(e.g., from v16 to v18\), the ABI changes, and the existing binary becomes incompatible, throwing 'Module did not self-register' or 'compiled against a different Node.js version'. Fix: Run \`npm rebuild\` \(or \`yarn rebuild\`/\`pnpm rebuild\`\) to recompile all native modules for the current Node.js ABI. More reliably: Delete the \`node\_modules\` folder and the lockfile \(\`package-lock.json\`/\`yarn.lock\`\), then run \`npm install\` to force a fresh build of all native modules for the current Node version.

Journey Context:
Developer uses nvm to switch from Node 16 to Node 18 to test a feature. Runs an existing project that uses \`bcrypt\` or \`sqlite3\`. Immediately crashes on startup with 'Error: The module was compiled against a different Node.js version. NODE\_MODULE\_VERSION 93. This version of Node requires NODE\_MODULE\_VERSION 108'. Developer remembers they just upgraded Node. Tries \`npm install bcrypt\` thinking it will reinstall, but it sees the binary is already there. Tries \`npm uninstall bcrypt && npm install bcrypt\`, which works but is slow. Eventually learns about \`npm rebuild\`, runs it, all native modules recompile quickly. App starts successfully.

environment: Projects with native dependencies \(bcrypt, sqlite3, pg-native, fibers\) when developers upgrade Node.js versions using nvm, n, or installing new LTS versions. · tags: native-module abi node_module_version rebuild node-gyp upgrade bcrypt nvm · source: swarm · provenance: https://nodejs.org/api/n-api.html\#abi-stability
