Hi, I wonder if anyone knows what is causing this issue? I am trying to run the rails installer but after entering my GIT info it gives me this error:
There has been an error
Error changing group of /opt/rix to rvm
The application will exit now
Thanks for any advice!
Brad

7,102 PointsAhh that sounds like a good possibility. I use Tower as my Github client and i found I had permission issues when trying to create a new folder in my 'sites' folder which sits in my user directory (if i understand correctly).
Not sure how i'd go about editing those permissions though?

39,199 PointsA quick search of the Treehouse from for /opt/rix
revealed:
It's a permissions error. The easiest way to fix it, is to run Repair Disk Permissions
on your hard drive.
- Open
Disk Utility
- Choose
Macintosh HD
- Click
Repair Disk Permissions

Its only going to work on Apple-specific files and files that are part of a package with receipts (see http://support.apple.com/kb/HT1452) so it can only set the permission back to what they are "supposed" to be and only for files that it knows what the permissions should be.

7,625 PointsI found what looks like the same issue over on GitHub, and it looks like a system reboot should resolve that and make it possible for you to install.
