Cannot load such file - Ruby / Compass / Susy

Question

When I run grunt, I keep getting the following error. I've installed, uninstalled, reinstalled them multiple times with the same issue. On a previous PC with the same installation files it worked fine, so I'm confused as to what is causing the issue?

I have the following installed:

• Ruby 2.1.5
• Node.js 0.10.26
• compass 0.12.2
• susy 1.0.9

The error is:

Answer 1

The problem is solved. My issue was that susy was installing a later version of sass. Once I removed that version and kept my old sass version, I was able to run grunt with out issue.

I hope this helps someone else too.
