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


Translate

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?

    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.

    I ran into this problem when I used the latest version of Ruby (currently 2.2.1) as stated on the OpenShift setup instructions. I fixed it by:

    1. Installing Ruby 1.9.3
    2. Re-running "gem install rhc"

    After that, I was able to run "rhc setup" without any issue.

    If you are running Windows 10 Pro x64, try installing Ruby 2.1.8 (x64) with Git Version 2.7.0. This will surely allow you to run rhc setup as it did happened with me. Earlier I had a problem running & installing latest version of Ruby 2.2.4 (x64) but when I downgraded to ruby version 2.1.8 (x64) I was able to run rhc setup and configure OpenShift client toolson Windows. See the image for Ruby version I'm using - ruby 2.1.8p440 (2015-12-16 revision 53160) [x64-mingw32]

    enter image description here

    Read here for getting started to OpenShift client tools on windows.

    Use the RHC tested Ruby version instead of the latest. As of today it is 1.9.3-p194

    Try using/installing a lower version of ruby after uninstalling the 2,2,0 because some windows version conflict with ruby version you are using. I tried 2.2.3 and then lowered to 2.2.0 and it worked for me.

    I ran into this same error, and none of the solutions worked for me. In a last attempt, I installed the Ruby 1.9.3-p551 version and the rhc setup went smoothly. I use a Windows 10 machine.

    I am running Windows 10 Pro x64. I installed Ruby 2.1.8 (x64) with Git Version 2.7.2. Rhc was installed successfully. However, "rhc snapshot save ..." command had problem with net-ssh. However, after restarting windows 10 the errors was gone.

    Remember to try reboot your windows.
