Report #4901

[bug\_fix] Error: The module '/path/to/bcrypt.node' was compiled against a different Node.js version using NODE\_MODULE\_VERSION 72. This version of Node.js requires NODE\_MODULE\_VERSION 93.

Rebuild the native modules from source for the current Node version using npm rebuild, or completely wipe node\_modules and package-lock.json and run npm install fresh. For frequently switching Node versions, use npx rimraf node\_modules && npm install after switching. The root cause is that native C\+\+ addons \(.node files\) are compiled against a specific Node.js ABI \(Application Binary Interface\) version and must be recompiled when Node major versions change.

Journey Context:
You use nvm to switch from Node 14 to Node 16 to test a feature. You run npm start and it immediately crashes with ERR\_DLOPEN\_FAILED mentioning NODE\_MODULE\_VERSION 83 vs 93. You check the path and it's a .node file inside bcrypt or sqlite3. You try npm install again but it says everything is up to date. Realizing that native C\+\+ addons bind to specific Node.js ABI versions, you understand the .node binary was compiled for the old Node version. You run npm rebuild which recompiles the native modules against the current Node headers. The error goes away. You learn to always reinstall dependencies after major Node upgrades.
