RVM (Ruby Version Manager) 1.0.0

RVM 1.0.0, Ruby 1.9.2 and Rails 3.<p>+ Rubinius will remove the GIL ("the work has already begun" -- Yehuda Katz <a href="http://yehudakatz.com/2010/08/14/threads-in-ruby-enough-already/" rel="nofollow">http://yehudakatz.com/2010/08/14/threads-in-ruby-enough-alre...</a>)<p>+ MacRuby will be even faster, more stable and more documented<p>It will be an awesome end of 2010/2011 for Ruby programmers.

This is one of those tools that you don't realize you're missing until you start to use it.<p>On OS X, the entire process of installing was painless, straightforward, and took very little time. The process of learning it took even less time.<p>Highly recommended.

Here is a nice post on RVM (and Perlbrew): <i>Two tools you should be using, if you aren't already</i><p><a href="http://ithaca.arpinum.org/2010/06/13/rvm-and-perlbrew.html" rel="nofollow">http://ithaca.arpinum.org/2010/06/13/rvm-and-perlbrew.html</a>

I use RVM for all Ruby installations now. I can't think of a distro or UNIX flavour whose Ruby packages are so good that I would use them instead of RVM. That includes Gentoo, Debian, Ubuntu, CentOS, BSD, OSX.<p>For those developing Ruby libraries, RVM makes multi-version testing a breeze.

At MWRC 2010 I wandered just outside the auditorium and ran into Wayne. I don't think we'd formerly met before, but we got to chatting and I told him I had played around a bit with RVM, but had some questions/issues.<p>Holy shit. I got the world's greatest crash course on, not just RVM, but bash scripting as well.<p>Wayne is not only a really nice guy and fun to hang with, but freakin' <i>smart</i>.<p>Super congrats on reaching 1.0.0.

RVM is so full of awesome. Specifying a project's gemset with an .rvmrc file is my preferred workflow now. Its a genius tool.<p><a href="http://rvm.beginrescueend.com/gemsets/basics/" rel="nofollow">http://rvm.beginrescueend.com/gemsets/basics/</a> <a href="http://rvm.beginrescueend.com/workflow/rvmrc/" rel="nofollow">http://rvm.beginrescueend.com/workflow/rvmrc/</a>

best feature: hopping on irc #rvm on freenode for instant assistance

If you develop Rails apps, and your not using RVM and gemsets... bless your heart.

For those who like rvm for its gemsets, check out rip: <a href="http://github.com/defunkt/rip" rel="nofollow">http://github.com/defunkt/rip</a> . Supports pushing/popping multiple ripenvs (gemsets) and has sweet support for unix-like command plugins.

rvm is sweet for managing rubies but not so sweet in that it hijacks cd(). I like to cd without any apps meddling.<p>Recommended fix: $ echo rvm_project_rvmrc=0 &#62;&#62; ~/.rvmrc

How does it compare to the more mature Virtualenv for Python?

Save so much time and energy with this tool. Realized how much more I get done on a daily basis because of it and almost felt guilty not to donate a few bucks.

RVM rocks I can't imagine working without it. Great to see it hit Version 1. Plus, Wayne is, hands down, one of the nicest guys I've ever met.
