reinstall npm-ionic,bower,cordova but still problem not solved. please help me thank you

  1. Last resort. Restart your pc.
  2. This error is basically from ionic-cli, possible solutions kill all the npm server's running on your local machine.
  3. Remove the latest cli version and install an older version of ionic-cli.
