Unable to install any Ruby gems - undefined method `invoke_with_build_args`

Question

I installed Ruby 2.1 from rubyinstaller.org on my Windows 7 system.

While trying to install any gem, I am facing the following error:

C:\Ruby21>gem install compass
ERROR:  Loading command: install (Win32::Registry::Error)
    The system cannot find the file specified.
ERROR:  While executing gem ... (NoMethodError)
    undefined method `invoke_with_build_args' for nil:NilClass

I've no clue what's wrong.

Try opening the thing that is 30 years behind the unix shell aka Commandprompt with admin access. Then rerun your command as admin. — AME, Dec 01 '14 at 16:19
@МалъСкрылевъ Weird. It returns the exact same error. No trace. — Anil Dewani, Dec 01 '14 at 20:46
Well, can advice only use other shell , Cygwin or mingw or etc — Малъ Скрылевъ, Dec 01 '14 at 21:11

Try to reinstall again the ruby package using cygwin installer. Even if they are the same version.
