Fixing 'Cannot Find Module' Error in Node.js: A Complete Guide

The 'Cannot Find Module' error in Node.js occurs when the required module cannot be found at runtime.

This can happen due to incorrect module paths, missing dependencies, or misconfigured package files.

To fix this error, start by checking that the module is correctly installed.

You can run npm install to ensure all dependencies in your package.json are installed.

If the error persists, verify the module’s path and ensure you are requiring it correctly.

For local modules, ensure that the path is relative and correctly points to the file’s location.

If you are working with global modules, try reinstalling them or using npm link to create symlinks.

Additionally, check the node_modules directory to confirm that the module is present.

If you're using TypeScript, ensure that type declarations for the module are available.

You can also use require.resolve() to debug the path resolution process.

Finally, if working with external libraries, ensure that they are compatible with your Node.js version.
