npm cache clear –drive

# Install the dependencies

npm set up

– Ensure React-scripts Are Present within the Dependencies Object

Ensure that the react-scripts are current within the dependencies object, not within the devDependencies. The program will carry on displaying the error till the react-scripts aren’t discovered within the dependencies. Let’s take an instance for higher understanding.

Example:

{

“dependencies”: {

“react-scripts”: “5.0.0”,

“react”: “^18.0.0”,

“react-dom”: “^18.0.0”

}

}

The react-scripts shouldn’t be put in globally. Moreover, they need to be a undertaking dependency. Installing it globally might battle with the model the programmer is at the moment utilizing and trigger a number of different points.

– Delete Package-lock.json & Reinstall

The dependency tree utilized by npm and different related package deal managers for JavaScript-based purposes, together with react apps, is mirrored within the package-lock.json file. Every time the package deal.json or node modules tree is modified, it’s up to date.1674319732 225 Sh React Scripts Command Not Found Fixing This Error

When updating this file, errors can often occur (and often for unknown causes). The quickest repair is utilizing the npm set up command to recreate the file from scratch.
