Vercel automatically configures the build settings for many front-end frameworks, but you can also customize the build according to your requirements.

Hi @Zhaolin Lau. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
The error message ERROR packages field missing or empty from pnpm during your Vercel build suggests that your project is being treated as a pnpm workspace, but the required packages field is missing or empty in your pnpm-workspace.yaml file.
This is not a Nuxt-specific error, but rather a pnpm configuration issue. The knowledge sources do not explicitly mention this exact error, but they do confirm that Nuxt projects can use pnpm as a package manager and that the pnpm-lock.yaml file is important for dependency management in Nuxt projects. If you are not intentionally using a monorepo/workspace setup, you may have an unnecessary pnpm-workspace.yaml file, or it may be misconfigured.
To resolve this:
- If you are not using a monorepo, delete the pnpm-workspace.yaml file from your project root.
- If you are using a monorepo, ensure that your pnpm-workspace.yaml file includes a valid packages field, for example:
This tells pnpm where to find your packages.
If you need more details on pnpm usage with Nuxt, see the official Nuxt documentation for installing dependencies and project structure, which confirms that pnpm is supported and that the lockfile is important for reproducible builds, but does not provide further troubleshooting for this specific errorDocs > 4.x > Guide > Directory-structure.
If you continue to have issues, double-check your project structure and ensure your configuration files are correct.
