node .output/server/index.mjs after building your Nuxt app results in a quiet exit (no errors, no server), there are a few possible causes based on the knowledge sources:
1. Empty or Incomplete .output FolderIf the
.output directory is empty or missing critical files (like server/index.mjs), the server cannot start. This can happen if the build process did not complete correctly or if there is a misconfiguration. One user experienced an empty .output folder after a major refactor, and the solution was to create a fresh Nuxt project and carefully copy files over, which resolved the issue and allowed the build to generate the expected output files. This suggests that subtle configuration or project state issues can cause the build to silently fail to produce a runnable server output. Try creating a new Nuxt project and migrating your code incrementally to isolate the problem source Nuxt3 build .output folder remains empty, nothing copied from .nuxt.
2. Volume Mounts Overwriting .output in DockerIf you are running your app in Docker and using a volume mount that overwrites the
.output directory, the server entrypoint may not exist inside the container, causing a quiet exit. Removing the volume mount for .output resolved the issue for another user How to run Nuxt3 with docker (docker compose).
3. Node Version or Dependency IssuesSometimes, missing dependencies or an incompatible Node version can cause the server to fail silently. Make sure you are using a supported Node version (e.g., Node 18 or 20) and that all dependencies are installed. Deleting
node_modules, lock files, and reinstalling dependencies before rebuilding has resolved similar issues for others Cannot find module '@vue/shared' when running node .output/server/index.mjs after Nuxt 4 build.
4. Check for Build Warnings or ErrorsEven if the build command appears to succeed, check the logs for any warnings or errors that might indicate why the output is incomplete or invalid. Recommended Steps: - Delete
.output, .nuxt, node_modules, and your lock file (pnpm-lock.yaml or package-lock.json).
- Reinstall dependencies: pnpm install
- Rebuild: pnpm run build
- Ensure .output/server/index.mjs exists and is not empty.
- Run: node .output/server/index.mjs
If the problem persists, try creating a fresh Nuxt project and migrating your code as described above.
If none of these steps resolve the issue, the knowledge sources do not provide a more specific solution for a completely silent exit with no errors. In that case, further debugging (such as adding console.log statements to index.mjs or running with increased verbosity) may be necessary.

@kapa.ai Build seems to succeed - I get a non empty index.mjs but at the end of the build I get this:
@nuxt/image 11:21:35 AM] WARN sharp binaries for linux-x64 cannot be found. Please report this as a bug with a reproduction at https://github.com/nuxt/image.
Let me check the knowledge base for you again. One moment! :books:
----------------------
The warning you are seeing:
indicates that the Nuxt Image module (which uses the
You need to ensure that
sharp library for image processing) cannot find the required native sharp binaries for your platform during the build. This is a common issue when deploying to a different environment (e.g., a Linux server) than your local development machine.
Key points from the knowledge sources:
- This warning means the sharp module is not properly installed or its binaries are missing for your target platform. This can happen if you build on one OS and deploy to another, or if the environment is missing build tools or dependencies required by sharp nuxt/image module in nuxt 3 causes problem in production.
- Even if you install sharp, you may need to rebuild it for your specific platform. One solution is to run:
after installing sharp on your production server. This ensures the correct binaries are built for your deployment environment nuxt/image module in nuxt 3 causes problem in production.
- The Nuxt Image documentation also mentions that if you encounter errors related to sharp and node-gyp, it is likely due to your OS architecture or Node.js version not being included in pre-built binaries, requiring a build from source. They recommend checking the sharp installation documentation for requirements Get Started - Installation.
Summary:You need to ensure that
sharp is installed and its binaries are built for your deployment environment. Try running the rebuild command above on your server after installing dependencies. If the issue persists, consult the sharp installation docs or open an issue with a reproduction as the warning suggests.
If you need more detailed troubleshooting steps, let me know!
