npm start error with create-react-app

Question

I have a project who I didn\'t touch for 2 weeks. I take it back and now when I try to run npm start I got this error.

> react-scripts start
         


        

Answer 1

This occurs when the node_modules gets out of sync with package.json.

Run the following at the root and any sub service /sub-folder that might have node_modules folder within it.

rd node_modules /S /Q
npm install
