This error often happens when native modules fail to load correctly. Rebuild dependencies using npm rebuild or clear node_modules.
Problem
You may see this error in Node.js:
TypeError: Cannot read property 'bindings' of null
This usually happens when native dependencies are mismatched, often when using packages like bcrypt, sqlite3 or others that are compiled with native bindings.
Solution
This happens when:
- Node.js version changes but modules aren’t rebuilt.
- Native packages are not compatible with your Node version.
- You’re using a broken or outdated module.
Here’s how to fix it:
Step 1- Delete node_modules and package-lock.json
rm -rf node_modules package-lock.json
Step 2- Reinstall Dependencies
npm install
Step 3- Rebuild Native Modules
Use this when working with Electron or after switching Node versions:
npm rebuild
Or for more control:
npx node-gyp rebuild

Step 4- Check Compatibility
Make sure your native module (e.g. bcrypt, sharp, sqlite3) is compatible with your current Node.js version.
Check in the module’s documentation or run:
npm info <package-name>
Conclusion
This is caused by broken or misaligned native bindings. Reinstalling modules and rebuilding native packages should fix the issue. Always check version compatibility.
