Problem with npm start (error : spawn cmd ENOENT)
Solution 1
Set your environment variable to C:\Windows\System32 . This works for me.
Solution 2
If the first one doesn't work follow the 2nd steps. Navigate to your project folder and type this command >>>
rm -rf node_modulesrm package-lock.jsonrm yarn.locknpm cache clear --forcenpm installSolution 3
Downgrade react-scripts in package.json file
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@2.1.8npm startAfter that the app worked for me again.
