npm start doesn't works

[kvedantmahajan]

On windows, this project ran fine.

However, on my Mac. Following the same steps gives me an error

sh: react-scripts: command not found
npm ERR! file sh
npm ERR! code ELIFECYCLE
npm ERR! errno ENOENT
npm ERR! syscall spawn
npm ERR! advanced-react-patterns-v2@1.0.0 start: `react-scripts start`
npm ERR! spawn ENOENT
npm ERR!
npm ERR! Failed at the advanced-react-patterns-v2@1.0.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/vedant/.npm/_logs/2018-11-25T05_46_33_446Z-debug.log

I tried

1. rm -rf node-modules && npm install && npm start
2. npm i -D react-scripts && npm start

And it still fails

@kushalmahajan could you provide more details about that error? It might be a conflict in the dependency tree. I was getting a similar error because of a conflict with the eslint version.

I edited the package.json file, and changed the react-scripts version manually to 1.1.4 and that did the trick for me.

I lost track of it after all this time :(

Even I had the same issue today. @spacebromx solution helped though.

Try to delete the node_modules folder and reinstall the dependencies.
