Report #88781

[bug\_fix] Error: Cannot find module '../build/Release/bcrypt\_lib.node' Require stack: - /app/node\_modules/bcrypt/bcrypt.js

Run npm rebuild to recompile native addons for the current Node.js version and architecture, or delete node\_modules and package-lock.json \(or pnpm-lock.yaml\) and run install again. If on Apple Silicon \(M1/M2\) with a lockfile created on Intel Macs, ensure you are not running Node under Rosetta \(arch -x86\_64\) or vice versa.

Journey Context:
Developer clones a repository on their new M1 MacBook Pro \(ARM64\). They run npm install and it appears to succeed. When they run node index.js, it crashes with 'Cannot find module' pointing to bcrypt\_lib.node or some other .node file. They check node\_modules/bcrypt/build/Release/ and the file exists. They realize the binary was compiled for the wrong architecture - the lockfile was created by teammates on Intel Macs \(x86\_64\), and the prebuilt binary downloaded was for x64, but their Node.js is ARM64. Or alternatively, the binary was compiled for ARM64 but they are accidentally running Node under Rosetta. They delete node\_modules and package-lock.json, run npm install again \(forcing a rebuild for the correct arch\), and the app starts.
