so I was following a guide to install ruby and ROR 3, when I came to
the command:

bash < <( curl https://rvm.beginrescueend.com/releases/rvm-install-head )

When I run this command, get the following output:

Initialized empty Git repository in /usr/local/rvm/src/rvm/.git/

remote: Counting objects: 5929, done.

remote: Compressing objects: 100% (2846/2846), done.

Resolving deltas: 100% (3892/3892), done.

Unrecognized option: –prefix,

with the offending line being the "Unrecognized option: –prefix"

I’m not sure how to resolve this, but the install breaks at that line. I’ve tried removing the git directory and reinstalling to no avail.

Any help would be appreciated
