ruby - rhc setup gives error `no such file dl/import`

Question

I'm installing openshift client tools as described: https://developers.openshift.com/en/getting-started-windows.html#client-tools. On step 'Setting up Your Machine' I got error:

rhc setup C:/Ruby22-x64/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require' : cannot load such file -- dl/import (LoadError)

I found same problem: https://groups.google.com/forum/#!topic/supmua/hPyTTamhTyc It's suggest to replace DL with Fiddle.

How I can get working rhc?

Answer 1

Updating net-ssh to 2.9.3.beta1, as cremno suggested in this comment, resolved my problem.

gem install net-ssh -v 2.9.3.beta1

Before that, I tried gem install net-ssh, but it didn't help.
