Error when starting the server on react js, what should I do?

Question

JavaScript

Created an application - create-react-app app. Run - npm start.

Answer 1

added a variable to the user's PATH environment - C:\Windows\System32

Answer 2

Perhaps there was a problem with the modules during installation, try deleting node_modules and re-run npm install
