I have node v: 10.15.0, npm v: 6.4.11
and I'm trying to install JHipster. the files generation worked fine but when it runs `npm install` I got this error:

```
npm ERR! Unexpected end of JSON input while parsing near '....0.2","null-loader":"'

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\chiheb\AppData\Roaming\npm-cache\_logs\2019-01-07T21_05_15_281Z-debug.log

```

this is the end of the log file:

I think the problem is in the package.json file generated by Jhipster but I couldn't find the mistake in it.
