I'm install ruby 2.1.2 via rbenv, and rbenv is installed by homebrew on my MAC OSX 10.9.2, ruby global is successful set to 2.1.2, but when i try to run gem install, get some errors below.
MacBook-Pro:~ user1$ gem install bundler
ERROR: Loading command: install (LoadError)
cannot load such file -- zlib
ERROR: While executing gem ... (NoMethodError)
undefined method `invoke_with_build_args' for nil:NilClass
How to solve it, does anyone faced same problems before?
