OK, it drives me crazy! I try to run ruby / rails.
MacBook-Pro-2:Library me$ rvm list
rvm rubies
ruby-1.9.3-p194 [ x86_64 ]
ruby-2.1.0 [ x86_64 ]
# => - current
# =* - current && default
# * - default
MacBook-Pro-2:Library me$ rvm use 2.1.0
Using /usr/local/rvm/gems/ruby-2.1.0
<internal:gem_prelude>:1:in `require': cannot load such file -- rubygems.rb (LoadError)
from <internal:gem_prelude>:1:in `<compiled>'
MacBook-Pro-2:Library me$gem list
<internal:gem_prelude>:1:in `require': cannot load such file -- rubygems.rb (LoadError)
from <internal:gem_prelude>:1:in `<compiled>'
I provide any information to solve that problem. What is wrong? I can't find a solution so far.
I would recommend uninstalling ruby-2.1.0 and then reinstalling it as it seems like your current installation is corrupted.
rvm uninstall 2.1.0
rvm install 2.1.0
