I'm going through a server setup guide and I'm trying to download rubygems: 

gem update --system

I am on version 2.2.2 of ruby gems, version 2.1.2p95 of ruby, and ubuntu 14.04, but it doesn't appear to be working. Looking further into this, I found an alternative to the command here on their official site.

However, when I run:

~/ruby-src/ruby-2.1.2$ sudo gem install rubygems-update

I'm still getting the same error which is:

ERROR:  Loading command: install (LoadError)
cannot load such file -- zlib
ERROR:  While executing gem ... (NoMethodError)
undefined method `invoke_with_build_args' for nil:NilClass

  • As for me, use bundler and you will not have any of this problems. – Eugene Tkachenko Feb 23 '15 at 16:59
