If you are encountering the error message “‘react-scripts’ is not recognized as an internal or external command” while working with a JavaScript project using React, there are a few steps you can take to resolve this issue.
Potential Reasons for the Error
There are a few potential reasons why you might be encountering this error:
1. Missing or outdated dependencies: The ‘react-scripts’ package, which is responsible for providing scripts and configuration for React applications, may be missing or outdated in your project’s dependencies.
2. Incorrect environment configuration: It’s possible that your development environment is not properly configured to recognize the ‘react-scripts’ command.

Possible Solutions
Here are a couple of solutions to fix the ‘react-scripts’ not recognized error:
Solution 1: Reinstall Dependencies
One common cause of this error is missing or outdated dependencies. To resolve this, you can try reinstalling the project dependencies:
1. Open your project’s root directory in a terminal.
2. Delete the ‘node_modules’ directory by running the following command:
rm -rf node_modules
3. Clear the package cache by running the following command:
npm cache clean --force
4. Install the project dependencies again by running:
npm install
5. Once the installation is complete, try running the ‘react-scripts’ command again. The error should be resolved if the missing or outdated dependencies were the cause.
Solution 2: Update Node.js and npm
If reinstalling the dependencies did not resolve the issue, it’s possible that your Node.js or npm version is outdated. Updating them to the latest version can sometimes fix compatibility issues:
1. Check your current Node.js version by running the following command:
node -v
2. Compare your version with the latest stable version available on the official Node.js website (https://nodejs.org/). If your version is outdated, proceed to the next step.
3. Download and install the latest stable version of Node.js for your operating system from the official website.
4. Once the installation is complete, check your npm version by running the following command:
npm -v
5. Compare your version with the latest stable version available on the official npm website (https://www.npmjs.com/). If your version is outdated, proceed to the next step.
6. Update npm to the latest version by running the following command:
npm install -g npm@latest
7. After updating Node.js and npm, try running the ‘react-scripts’ command again. The error should be resolved if the outdated versions were causing the issue.

Solution 3: Check Environment Variables
In some cases, the error may be due to incorrect environment variable configurations. Follow these steps to verify and update the environment variables:
1. Open the environment variables settings on your operating system. The steps may vary depending on your OS.
2. Look for the ‘PATH’ variable in the system variables section.
3. Verify that the path to the directory containing the ‘react-scripts’ command is included in the ‘PATH’ variable. By default, the ‘react-scripts’ command is located in the ‘node_modules/.bin’ directory of your project.
4. If the path is missing, add it to the ‘PATH’ variable by editing it and appending the path using the appropriate delimiter for your OS. For example, in Linux or macOS, you can use the colon ‘:’ as the delimiter. In Windows, use a semicolon ‘;’.
5. Save the changes and restart your terminal or command prompt.
6. Try running the ‘react-scripts’ command again. The error should be resolved if the environment variable was misconfigured.
Alternative Idea: Use npx
Instead of directly running the ‘react-scripts’ command, you can use the ‘npx’ command to run it without the need for global installation:
1. Open your project’s root directory in a terminal.
2. Instead of running ‘react-scripts’ directly, use the following command:
npx react-scripts
3. This will automatically find and run the ‘react-scripts’ command in your project’s ‘node_modules’ directory.
4. Check if the error still occurs. Using ‘npx’ eliminates the need for global installations and can help bypass the ‘react-scripts’ not recognized error.
Best Practices
To avoid encountering the ‘react-scripts’ not recognized error in the future, consider following these best practices:
1. Always keep your project dependencies up to date. Regularly update your project’s dependencies to ensure compatibility and access to the latest features and bug fixes. Use the ‘npm outdated’ command to check for outdated dependencies.
2. Use a version management tool like ‘nvm’ (Node Version Manager) to manage multiple versions of Node.js on your machine. This can help ensure that your projects use the correct version of Node.js and avoid compatibility issues.
3. When working on a team, make sure all team members are using the same versions of Node.js and npm to avoid potential compatibility problems.
