Ionic IOS Add Error


I built my app with ionic in my windows machine. I copied it and am trying to add ios platform on my friends mac. Whenever I open the terminal and run “ionic platform add ios” I get:

There is an erorr in your gulpfile:
ERROR: EACCESS: permission denied, open '/Users/jim/.config/configstore/bower-github.json’
You don’t have access to this file.

I’m not use to macs, so I’m a bit lost.
