I've got some problem with starting app by using 'npm start'. After create react files folder and using that command I can see:

```
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! weatherapp@0.1.0 start: `react-scripts start`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the weatherapp@0.1.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

```

I want to add that I've used react before. I was running code the same way but everything was good. What's the solution?
