Problem with npm start (error : spawn cmd ENOENT)

Question

I have a problem with my application. Because before when I created an application it worked, but now, it shows me this error and I do not know why and the things I have to

Answer 1

I had the same problem after I tried to install Mongo DB. I found out that this problem only exists with react-scripts@3.0.0. Try to reinstall your npm with a different react script version. Simply go to your folder in command and reinstall like this:

npm install react-scripts@2.1.8
npm start

After that the app worked for me again.
