npm ERR! Unexpected end of JSON input while parsing near '...:"~0.0.0","webpack-de'

What I have tried :
1. npm cache clean --force
2. npm cache verify

Try:

   sudo npm uninstall -g @angular/cli
   npm cache clean --force
   sudo npm install -g @angular/cli@7.0.1 // older version of cli

Hope This helps
