Report #101931

[bug\_fix] Error: The module was compiled against a different Node.js version using NODE\_MODULE\_VERSION 108. This version of Node.js requires NODE\_MODULE\_VERSION 115.

Run npm rebuild or rm -rf node\_modules && npm install while using the Node version that will run the app. If you use nvm/fnm, ensure install and runtime versions match, or switch to a package that distributes N-API/prebuilt binaries for your target Node version.

Journey Context:
You installed dependencies under Node 18, then later nvm use 20 and start the app. It crashes at startup naming a .node file and showing NODE\_MODULE\_VERSION 108 versus 115. You look up the version numbers and learn 108 maps to Node 18 and 115 to Node 20. The native addon was compiled against the V8 ABI of Node 18, so Node 20 refuses to load it. You either run npm rebuild while on Node 20 to recompile the addon, or wipe node\_modules and reinstall. The fix works because C\+\+ addons embed an ABI version that must exactly match the V8/Node binary that loads them; prebuilt binaries must also be selected for the exact runtime version.
