Next command not found


If you are getting the error 'next' is not recognized as an internal or external command, operable program, or batch file, then this blog will help you fix this annoying issue. I will tell you what has worked for me!

The error message 'next' is not recognized as an internal or external command, operable program or batch file occurs when we overlook installing the necessary dependencies in a Next.js project.

To address this, you will have to incorporate Next.js commands into the scripts section of the package.json file instead of running them directly from the terminal.

Fix 1: Adding NextJS in package.json

In a Next.js project, the package.json file serves as a configuration guide for the various commands and dependencies used within the project. One common feature is the inclusion of predefined script entries for actions like starting the development server or building the application.

If the package.json file does not contain a reference to "next" in its scripts section, it indicates that these Next.js-related commands have not been set up within the project.

Begin by accessing the package.json file within your project directory. This file is typically located at the

Is the console/terminal opened in the root folder with the file? What does the part of the package.json file look like (post it).

Is the console/terminal opened in the root folder with the file?

What do you mean by that? I opened the terminal inside VS Code.

What does the part of the package.json file look like (post it).

This is the package.json file:

This is a Next JS boilerplate I made a few weeks before, now it is not running the command anymore. I also habe some issues with webpack, is it possible that it has something to do with that?

Next not found in deploying teh >Next project on the Azure App Service

Hi Habiba Asif,

Your Next.js app is running on Azure App Service with (Microsoft Entra authentication) . This is blocking your app’s API call to because the request isn’t .

The error means your app the Azure domain yet. You'll need to your app’s authentication settings to recognize the Azure domain as a trusted host.

Your app before because Easy Auth . Once you enabled Microsoft Entra authentication, it started blocking all requests—including those to your NextAuth.js API routes—causing the current authentication issue.

Option 1: Allow NextAuth.js to manage authentication

1). Disable Azure Authentication (Easy Auth):

  • Go to your App Service → Authentication
  • Turn off

2). Update your config to trust the Azure domain

3). Set environment variables in Azure App Service -> Configuration

NextAuth.js Deployment

4). Redeploy and Restart the App

Option 2: Keep Azure Authentication enabled

If you need Azure Easy Auth (e.g., for corporate sign-in), you’ll need to configure it so it doesn’t block your API endpoints:

  • Go to App Service -> Authentication
  • Set to
  • Let your app handle

    Why am I not fit to start my application?

    @lasjorg Thanks for your answer!

    That doesn’t really tell us anything, what isn’t working, how isn’t it working, what happens when you run the command?

    When I dash the command or or I always get this message:

    lasjorg:

    What happens when you run from inside the root Next.js app folder? Is the CLI not working?

    No it is not working. I get the same message:

    lasjorg:

    I would try removing the node_modules folder and reinstalling the dependencies if not.

    I already did that a few times, but nothing changed.

    As I said, I am not able to start the server so I can not observe an error message in the console and all I got is:

    My apprehension was that I messed up something within the folder structure, but when I try to open older versions (which worked before) I receive the same message.

    I think I need to start a modern Next JS project from scratch and then copy and paste the files into the novel project and connect everything again from scretch. This should serve , but anyway it would be great to know what is the probleme here.

    I am fit to start other projects, but this one I am not able to start any version. All versions will give
