I have installed nodemon using these commands
npm install nodemon
npm installed successfully,
after running nodemon server.js
showing error
'react-scripts' is not recognized as an internal or external command,
operable program or batch file.
[nodemon] app crashed - waiting for file changes before starting...
Perhaps could you try installing and saving the react-scripts dependency and seeing if this resolves your issue:
npm i -S react-scripts
Hopefully that helps!
