I just installed Ruby then I download rubygems 1.6.1 and I extract the zip dir.. cd to the dir and do ruby setup.rb... and this is what I get:

RubyGems 1.6.1 installed

=== 1.6.1 / 2011-03-03

Bug Fixes:

  • Installation no longer fails when a dependency from a version that won't be installed is unsatisfied.
  • README.rdoc now shows how to file tickets and get help. Pull Request #40 by Aaron Patterson.
  • Gem files are cached correctly again. Patch #29051 by Mamoru Tasaka.
  • Tests now pass with non-022 umask. Patch #29050 by Mamoru Tasaka.

RubyGems installed the following executables:


I tough gems was installed but when I do "gem install rails" i get :

ERROR: Loading command: install (LoadError)

no such file to load -- zlib

ERROR: While executing gem ... (NameError)

uninitialized constant Gem::Commands::InstallCommand

So I guess something went wrong or gem is not installed can you help me?

    Sounds like you don't have Ruby installed with zlib enabled.

    If you're using RVM, this is pretty easy:

    You'll probably need OpenSSL too:
