Sh: React-scripts: Command Not Found After Running Npm Start

sh: react-scripts: command not found after running npm start

If you are a JavaScript developer working with React, you might have encountered the error message “sh: react-scripts: command not found” after running the “npm start” command. This error can be frustrating, but don’t worry, there are a few solutions to fix it.

Solution 1: Check if react-scripts is installed

The first thing you should do is check if the “react-scripts” package is installed in your project. This package is required to run React scripts, so if it’s missing, you will encounter the “command not found” error.

To check if “react-scripts” is installed, open your project’s terminal and run the following command:

npm ls react-scripts

If the package is not installed, you can fix the issue by installing it locally:

npm install react-scripts

Solution 2: Clear the npm cache

Sometimes, the error can be caused by a corrupted npm cache. To fix this, you can clear the cache and try running the “npm start” command again.

To clear the npm cache, run the following command:

npm cache clean --force

After clearing the cache, try running “npm start” again and see if the error persists.

Solution 3: Update npm and Node.js

If the above solutions didn’t work, it’s possible that your npm or Node.js version is outdated and causing compatibility issues.

You can update npm by running the following command:

npm install -g npm

For updating Node.js, you can visit the official Node.js website and download the latest version.

Conclusion

The “sh: react-scripts: command not found” error can be fixed by checking if “react-scripts” is installed, clearing the npm cache, or updating npm and Node.js. Try these solutions one by one and see which one works for you.

Remember to always keep your development environment up to date to avoid compatibility issues and ensure a smooth development process.

Happy coding!
