First go to the C:\Users\pcusername\ .ionicand
Just put this below code into your config.json and save it

{
  "state": {
    "doctor": {
      "ignored": []
    },
    "lastCommand": "2018-02-07T00:21:19.697Z"
  },
  "created": "2017-12-11T06:47:04.733Z",
  "daemon": {
    "updates": true
  },
  "devapp": {
    "knownInterfaces": []
  },
  "addresses": {},
  "git": {},
  "user": {},
  "tokens": {
    "appUser": {},
    "telemetry": "504683a3-978d-43a7-a485-cfc29f309212"
  },
  "backend": "pro",
  "telemetry": true,
  "yarn": false,
  "version": "3.19.1"
}

Or
try reinstalling your ionic again through npm
I hope your problem will be fixed
Good Luck
Thank you
