Solving the "React Scripts is not Recognized as an Internal or External Command" Error
If you’ve been working with React, chances are you’ve encountered the frustrating “react-scripts is not recognized as an internal or external command” error. This common issue can occur for a variety of reasons, but the good news is that it's usually straightforward to fix. Here, we’ll go through a few steps to get you back on track.
Understanding the Error
Before diving into the solutions, let’s briefly discuss what this error means. When you create a new React application using Create React App, a package called react-scripts is included in your node_modules directory. This package contains scripts and configuration used by Create React App, including the commands to start your development server, run tests, and build the project.
When you see the error message “react-scripts is not recognized as an internal or external command,” it usually means that the system is unable to locate react-scripts in your project’s node_modules. This can be due to various reasons such as:
Missing or corrupted node_modules
Misconfigured environment paths
Using an outdated version of Create React App
Steps to Resolve the Error
Step 1: Install or Reinstall Node Modules
The most common cause of this error is a missing or incomplete node_modules directory. Running the command below ensures that all the necessary dependencies are installed.
