'react-scripts' is not recognized as an internal or external command, operable program or batch file
It is an error about react-scripts file missing in your node modules directory at the time of installation.
Now, you can add manually this via the command:
npm install react-scripts
I had the same issue, resolved by simply running following command in the project root folder -
npm install react-scripts --save
I found the community answer, which is perfect solution
