试图在OSX Mountain Lion上安装Ruby / Rails

Question

This is my first question please be nice.

I've been trying to get my hands dirty with ruby/rails for a small coding project. I have Mountain Lion, and have been trying to use various techniques i've found on stackoverflow, and across the interwebs. It's not going so great! Nothing works of course. I have the system version of Ruby (1.8.7) as of now, and a bunch of broken junk from trying and failing to install Ruby!

When I install Rails via gem install, it sat for awhile... I finally learned to use -V, and noticed everything was returning back 302, and this takes forever, and finally it installs -- I get this output when I try to run rails -v

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:230:in `activate': can't activate rack (~> 1.4.5, runtime) for ["actionpack-3.2.13", "railties-3.2.13"], already activated rack-1.5.2 for ["rack-ssl-1.3.3", "railties-3.2.13"] (Gem::LoadError)

It looks like some dependencies are broken? Anyhow I'm now trying to use RVM now to get another version of ruby and setup grails with brew, This is telling me that I need a newer version of ruby to install anything pretty much?? Here is the output.

rvm install 1.9.2-head Installing requirements for osx, might require sudo password. Skipping brew update make sure your formulas are up to date. Cowardly refusing to continue, please read 'rvm autolibs'.

To proceed rvm requires a ruby-1.9|ruby-2 compatible ruby is installed. We attempted to install ruby automatically but it failed. Please install it manually (or a compatible alternative) to proceed.

-- I am getting os frustrated here, please throw me a bone and help me out --- If I have to have to I'll setup a linux vm just to get rails running -- yet I prefer working on my mac.

Please any advice?? I just want a working version of Rails 3 on my Mac this is allThanks in advance

Please go through www.railsinstaller.org for detailed installation and setup process. This guide should answer all of your questions.

Have you tried this tutorial http://net.tutsplus.com/tutorials/ruby/how-to-install-ruby-on-a-mac/ The tutorial includes all the errors you may come across during the installation. According to this tutorial Ruby on Rail comes with the mac out of the box.

Answer 3

Have you tried JewelryBox? It provides a painless install method for rvm and a great little gui that helps you monitor the size of your gem sets, and installs of ruby. Along with helpful reminders to upgrade rvm. I resisted at first using it, because using a GUI made me feel like a noob, but it really is a great little tool, that makes for super easy installs of ruby, and rvm, and consequently rails.
