We are upgrading to the latest ruby version (2.2.3) and latest rails version (4.2.4) and we can't get pass this error:

The error shows you are using the system Ruby, not RVM. You need to tell Pow to use the right Ruby version. You need to create a .rvmrc file specifying which Ruby to use, and also create or edit a .powrc or .powenv file to tell Pow to load RVM. See the Pow docs on using RVM.
