I installed RVM on my Ubuntu, and when I try to install Ruby, I get this error.
rvm install 2.0.0 # 'ruby' was not found, cannot install rubygems unless ruby is present (Do you have an RVM ruby installed & selected?) What could be wrong?
It is a known bug https://github.com/wayneeseguin/rvm/issues/2382
Click the Watch button on bottom of the page - or comment if you can provide more details.
This bug was fixed, a new stable version is released: 1.24.6.
