Now I am trying to run this command ionic cordova start helloWorld2 blank

But getting this error

[ERROR] Unable to find command: cordova start helloWorld2 blank

    You may need to be in an Ionic project directory.

Please let me know how I can overcome this issue.

Solution

Try uninstalling your current NodeJS version and reinstalling version 8.~ and then run

ionic start HelloWorld2 blank

then enter Y when asked if you want to integrate the app with Cordova.
