Troubleshooting the npm run build Issue in Next.js 14

If you’re facing challenges with the command npm run build not functioning in your Next.js 14 project, you’re not alone. This issue often arises due to certain dependencies not being installed correctly on your deployment server. In this guide, we’ll explore the problem in detail and provide a clear solution to get your project building smoothly.

Understanding the Problem

What Happens During the Build?

When you run npm run build, the process kicks off a series of tasks required to compile your Next.js application into a production-ready format. The command typically involves:

Compiling the Code: Ensuring the application's code is properly formatted and error-free.

Linting: Checking for any coding standard violations.

Generating Static Pages: Creating HTML files from your React components.

Collecting Data: Preparing dynamic data required for your app.

While this process generally succeeds on your local machine, issues can arise on the deployment server.

The Error on the Deployment Server

During a build on your deployment server, you may encounter an error log that resembles this:

This message indicates that the server could not find the next command, resulting in a failed build.

Why Does This Happen?

The primary reason for this issue is that the dependencies necessary for your Next.js project, including the Next.js package itself, may not have been installed on the deployment server. This typically occurs when the command npm install has not been executed in that environment.

Solution: Modify Your Build Script

To resolve this next: not found error during the deployment process, you simply need to ensure that the required packages are installed automatically before trying to build your application.

Steps to Fix the Issue:

Open your package.json file: This file contains scripts that define how your application should behave during different operations (like building or starting the app).

Locate the build script: You will find a section that looks like this:

Modify the build command: Replace the existing build command with the following line:

Here’s the updated scripts section:

What Does This Change Do?

npm i: This command installs all the dependencies listed in your package.json. By placing it before the next build command, it ensures that the necessary packages, including Next.js, are available on your deployment server.

next build: This part remains unchanged and continues to handle the actual build process.

Conclusion

The npm run build issue on deployment servers is a common obstacle faced by developers working with Next.js 14. By ensuring that the build script also installs dependencies first, you can mitigate the next: not found error and make your deployment process smoother.

If you continue to experience issues after applying this fix, consider double-checking your deployment environment or configurations. Good luck with your Next.js project, and happy coding!
