Cleaning up older rails installs on Mac OS X Snow Leapord

I am currently wanting to cleanup my gems so that i end up with Rails
2.3.11 and Rails 3.0.x. While working on this I notice I cannot
uninstall some Rails versions from command line. I ran the following
and wonder if it is safe for me to remove Rails 1.2.6, 2.2.2 and 2.3.5
versions from these folders on my Mac.

rails (3.0.7, 3.0.6, 3.0.5, 3.0.3, 3.0.0, 2.3.11, 2.3.8, 2.3.5, 2.2.2,
1.2.6)

Sounds like no fun. I would recommend just starting to use rvm, and
forget
about the mess. Rvm isolates your rubies, and gems so you wont have
interference from the system installs.

Ps, when I say rvm, also mean that in rvm you can create gemsets. Many
create a gemset for each project, so the dependencies of each project
are
seperate. Rvm also lets you insall as many versions of ruby that exist.
As
far as what you leave on your mac, the only thing you need to install
rvm is
one ruby, does not matter the version. As for all the other versions of
rails you should be able to delete them or leave the as you like.

I just ran into this last night. Since I use rvm for my gems now, I
ended up using ‘gem uninstall rails’ (outside of rvm) and choosing to
uninstall all of the available versions. I manually nuked the gem
repos under /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/
lib/ruby/gems/1.8. HOWEVER, I am unsure what ramifications this will
have outside of my rvm world. I’m thinking specifically of MacRuby.

YMMV, I’m not responsible for you breaking your machine. :wink:

I have been using RVM, Homebrew and POW in combination with projects
using Rails 2.3.11 retrofitted with Bundler and then separate projects
using Rails 3.0.x. Between my homebrew installs of MySQL, POW and
passenger issues depending on whether you use RVM and/or try to use
Rails 2.3.11… It has been fun to say the least. I have some issues
with the Mysql gem with one of my gemsets and have been trying to see
why one of my sites will run under RVM system, but not correctly under
the RVM gemset I created for the app.
I was hoping to clean up my system gems and move towards using more
RVM sets but sometimes you break more than you cleanup. In the end, I
will probably leave my system intact and use RVM for new projects
going forward. Still, there is the part of my brain that wonders why
Rails 1.2.6 and 2.2.2 are installed in their current locations. I have
a tendency to poke around places that were not meant to be poked in it
seems.
