Fix module not found errors in Next.js projects

Module not found errors happen when Next.js can't resolve an import path. This can be caused by missing dependencies, incorrect path aliases, or trying to import server-only modules in client components.

Error messages you might see

Module not found: Can't resolve 'module-name' in '/path/to/file'
Module not found: Package path ./subpath is not exported from package

Why this happens in AI-generated code

1

Missing or uninstalled dependency

AI-generated code frequently imports packages that aren't in your package.json, assuming popular libraries are always available.

2

Incorrect TypeScript path aliases

AI tools generate imports using @/ aliases without verifying your tsconfig.json paths configuration matches the expected mapping.

3

Importing server modules in client components

AI code may import Node.js built-in modules like 'fs' or 'path' in files that end up bundled for the browser, where those modules don't exist.

How to fix it

1

Install missing dependencies

Run `npm install <package-name>` for any missing packages. Check AI-generated import statements against your actual package.json.

2

Verify path aliases in tsconfig.json

Ensure your tsconfig.json has the correct `paths` and `baseUrl` configuration that matches the import aliases used in your code.

Frequently asked questions

Why does my IDE resolve the import but Next.js can't find it?

Your IDE may use different TypeScript settings than Next.js. The Next.js compiler has its own module resolution that may not match your editor's IntelliSense configuration.

How do I know if a package supports the App Router?

Check if the package exports separate client and server entry points. Packages that use Node.js APIs need 'use server' or must only be imported in Server Components.
