[Mac] Trouble Adding a Class (Known Issue?)

So I’m rather new to both C++ and Unreal, and I’m trying to add a class following this tutorial however I’ve encountered an issue that I think a few others have yet I still have not reached a solution.

As soon as I add anything to my class as in the tutorial I get this error

Command
/Users/Shared/UnrealEngine/4.6/Engine/Build/BatchFiles/Mac/RocketBuild.sh
failed with exit code 127

I’ve uninstalled mono, commented out some lines as per this suggestion and my scheme is editor Mac. I have no idea what else could be the issue, and I could really use some help because otherwise I’ve reached a brick wall in terms of progress.

I have resolved the issue, I’m unsure what exactly did it, as I also reinstalled unreal, but I think the issue may have simply been my forgetting to comment out other lines from the setupmono.sh file, I’ve now commented out 14-20, and it seems to be working.
