In my case  the problem had to do with not having enough file permissions for some files the react-scripts package installation was going to write to  What solved it was running git bash as an administrator and then running npm install --save react-scripts again

I have tried many of the solutions to this problem found on line  but in my case nothing worked except for reinstalling NVM for Windows  which I am using to manage multiple Node versions   In the installer  it detects installed Node versions and asks the user if they wish for NVM to control them  I said yes and NVM fixed all PATH issues  As a result  things worked as before  This issue may have multiple causes  but corrupted PATH is definitely one of them and  re installing NVM fixes PATH

It is an error about react-scripts file missing in your node modules  directory at the time of installation  Check your react-script dependency is avaliable or not in package json  If not available then add it manually via  npm install react-scripts --save

react-scripts is not recognized as an internal or external command is related to npm   I would update all of my dependencies in my package json files to the latest versions in both the main directory and client directory if applicable  You can do this by using an asterisk     instead of specifying a specific version number in your package json files for your dependencies   For Example    dependencies          body-parser             express             mongoose             react             react-dom             react-final-form             react-final-form-listeners             react-mapbox-gl             react-redux             react-responsive-modal              I would then make sure any package-lock json were deleted and then run npm install and yarn install in both the main directory and the client directory as well if applicable   You should then be able to run a yarn build and then use yarn start to run the application
