Report #15569

[bug\_fix] Error: The module '/path/to/node\_modules/bcrypt/lib/binding/napi-v3/bcrypt.node' was compiled against a different Node.js version using NODE\_MODULE\_VERSION 83. This version of Node.js requires NODE\_MODULE\_VERSION 108.

Delete node\_modules and package-lock.json \(or yarn.lock\) and run \`npm install\` to trigger a fresh compilation against the current Node.js headers. Alternatively, run \`npm rebuild\` or \`yarn rebuild\` to recompile only the native modules without reinstalling JavaScript dependencies. The root cause is that native C\+\+ addons are compiled against specific Node.js ABI \(Application Binary Interface\) versions represented by NODE\_MODULE\_VERSION; when upgrading Node.js \(e.g., v14 to v18\), the compiled .node binary is incompatible and must be recompiled against the new Node headers.

Journey Context:
A developer uses nvm or n to switch from Node.js 14 to Node.js 18 to test a new feature. They navigate to an existing project that uses \`bcrypt\` for password hashing and try to start the server. Immediately, they get a hard crash with a long stack trace mentioning NODE\_MODULE\_VERSION mismatch, stating the module was compiled for version 83 \(Node 14\) but current requires 108 \(Node 18\). The developer initially panics, thinking they broke their environment. They try downgrading Node back to 14, and it works again. Realizing the issue is version-specific, they search and learn about native module ABI compatibility. They try \`npm install\` again but it doesn't rebuild because the .node file already exists. They learn about \`npm rebuild\`, run it, and see node-gyp recompiling the native module against the Node 18 headers. The server then starts successfully. Alternatively, they might just delete node\_modules and reinstall, which achieves the same recompilation.
