Question

I’m new in Ruby on Rails, I’m trying to install rails on mac os x 10.6.8 (i already have ruby: ruby 1.8.7 (2010-01-10 patchlevel 249) [universal-darwin10.0]), but when I try to see the rails version installed using $ rails -v, I get:

rails is not currently installed on this system. To get the latest version, simply type:

I tried to run:

$ sudo gem install rails

You can then rerun your “rails” command.

Of course i tryed to type sudo gem install rails and others options too but no solution, also i tryed to install rvm, this is what i have:

$ rvm -v

rvm 1.13.0 (master) by Wayne E. Seguin <[e-mail]>, Michal Papis <[e-mail]> [https://rvm.io/]

how can i do to make it work together? or what can i do to fix the problem?

Answer 1

I was having the same problem when running OSX 10.7.4. I solved it with the following approach.

Identify the gem manager you’re using:

$ which gem 
/Users/peter/.rvm/ruby-1.9.2-p320/bin/gem

Then do a gem update for that specific version:

$ gem update --system 1.9.2

This took ages to complete, but once finished, rails -v returns:

Rails 3.2.8

Admittedly life shouldn’t be this hard. Although I’m used to command line stuff, I’d love to see a graphical tool that allows you to mix, match and confirm what Ruby/Gems are installed on your system.

I hope this helps.
