✅ Solution
The "ModuleNotFoundError" in vercel-cli CI typically arises from missing dependencies not installed during the build process. To fix, ensure that your `package.json` accurately lists all required dependencies, and that your build process includes a `npm install` or `yarn install` step before running vercel-cli commands. Double-check that any optional dependencies crucial for CI/CD are also installed.
