Are you on Windows?
You might not have the system path environment variable. Try to run this in your terminal, and then run the command again.
export PATH=$PATH:C:\Windows\System32

The react-scripts version 3.0.1 is avoiding to 'npm start'. I tried downgrading to version 2.1.8, it works fine. But I don't want to downgrade the version everytime to make my app work.
I tried following the similar case, but it didn't help.
Any one else facing the issue, please help to resolve it.
if you tried this and it didn't work for you then this maybe a react-scripts issue so to fix it try this:
remove node_modules and lock files
edit package.json so the version of react-scripts is "2.1.8"
npm install
npm start
LTK how that goes
I am installing a create-react-app.
I have already managed to do it few weeks ago, but this time it doesn't work. It throws an error when I do the command 'npm start'.
I followed the tutorial on reactjs.org.
I have uninstalled and reinstalled latest version of nodejs (v10.15.3). My version of npm is : 6.9.0.
Any clue to help to solve this issue? Thanks

Try downgrading your react-scripts dependency to ^2.1.8 in your package.json file.
It worked for me
I am not able to execute "npm start" command. I am getting this error while running this command.
node -v : v12.0.0
npm -v : 6.9.0
I have tried to reinstall all the software.
even I have also changed the port number and try to execute the code.

Just delete the node_modules folder, and reinstall npm modules.
npm install
Make sure all the global & local packages that are being used in the scripts are installed, in your case it could be webpack-cli & yarn wasn't installed globally & you are trying to access it using your script.
All Export & PATH environments are setup correctly
rm -rf node_modules && npm install
