I have followed the instructions for setting up Openshift on Mac here, but when I reach step 2 and write my Openshift login, the terminal enters a loop where it outputs 

"? You must enter a valid HighLine::String".

Does anyone know what that could be about?

EDIT: As requested, here is a copy/paste of the terminal output:

$ rhc setup

Starting Interactive Setup for OpenShift’s command line interface

We’ll help get you setup with just a couple of questions. You can skip
this in the future by copying your config’s around:

/Users/videre/.openshift/express.conf
/Users/videre/.ssh/

To connect to openshift.redhat.com enter your OpenShift login (email
or Red Hat login id):

After entering the id, I get an infinite loop of the following:

? You must enter a valid HighLine::String.

In case it is of any use/interest, here is the output when requesting the rhc version:

$ gem list rhc

*** LOCAL GEMS ***

rhc (0.97.17)

EDIT 2

Highline version:

$ gem list highline

*** LOCAL GEMS ***

highline (1.6.14, 1.5.0)

    It could be an old version of highline – can you do ‘gem list highline’ to see what version you have?

    EDIT:
    A similar issue as you described was fixed in highline 1.6.8, and this link http://www.dahotre.com/programmings/capistrano-problem-must-enter-valid-highline-string describes a similar problem.

    Can you try the following

    gem install highline --version 1.6.13
gem uninstall highline --version 1.6.14

    and see if that resolves your issue?
