npm install fails for ionic project

Question

Hi when i tried to install ionic-angular am getting this error

PS D:\ENDART\DART-MOBILE> npm install ionic-angular
npm ERR! Unexpected token } in JSON at position 423538 while parsing near '...gZvBqA=="
npm ERR!     }
npm ERR!   }
npm ERR! }
npm ERR! '

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\NIKITHRA\AppData\Roaming\npm-cache\_logs\2019-06-11T05_18_26_257Z-debug.log
PS D:\ENDART\DART-MOBILE>

I tried this solution. But didnt solve. Installing create-react-app gives npm ERR! shasum check failed and npm ERR! Unexpected end of JSON input while parsing near '...mojOzGIEI2rg0m24Yb5Oq'

PS D:\ENDART\DART-MOBILE> npm config set registry "https://registry.npmjs.com/"
PS D:\ENDART\DART-MOBILE> npm cache clear --force
npm WARN using --force I sure hope you know what you are doing.
PS D:\ENDART\DART-MOBILE> npm cache verify

How to solve this.

Answer 1

If you configure the HTTP_PROXY in your environment:

http://username:password@proxy.server.com:port

---

npm config rm proxy
npm config rm https-proxy

Then try this:

rm -f package-lock.json 

and then

npm install
