Getting stuck in the beginning of this tutorial "http://learn.ionicframework.com/videos/getting-started/"

Having trouble with installing ionic, see pic, dont know what to do?

I personally haven’t encountered this issue but it looks like other people have.

You might be able to find a solution at Cannot install ios-sim

Good luck!

Thank you for input, i´m a humble beginner at programming in general, gonna check it out!

You need to have xcode and the xcode command line utilities installed.
