Module not found: Can't resolve '...' / Cannot find module

What it means

Your code refers to a file or package that can't be found. Like a recipe that says 'see page 42' when page 42 was torn out.

How to fix it: paste this prompt into your AI builder

My build fails with "Module not found / Cannot find module". For the exact module in the error: if it's an npm package, install it and add it to package.json dependencies; if it's a local path, fix the import to the file's real location and exact casing, and check that path aliases like @/ are configured in tsconfig/jsconfig and the bundler. Search for other imports of the same missing module. Only fix the imports/dependencies involved.

If the AI can't fix it: manual steps

1. If it works locally but fails on Vercel/Netlify, check the file name casing: Linux servers treat Button.tsx and button.tsx as different files.
2. Make sure package.json and the lock file were committed/pushed.
