Fix ModuleNotFoundError

in Vercel CLI

Solution

The "ModuleNotFoundError" in Vercel CLI usually means a project dependency isn't installed or correctly specified. Ensure your `requirements.txt` (or `pyproject.toml` if using Poetry) lists all necessary Python packages and that Vercel executes `pip install -r requirements.txt` (or its equivalent) during the build process; double-check the build logs for installation errors. Alternatively, for edge functions, verify dependencies are correctly bundled or accessible within the specific edge function environment.
