Question

Update and Solution

I finally got everything working after
1. Uninstalling everything ruby-related in /usr/local/… as well as uninstalling all versions of rails.
2. Installing RVM as a standard user -> i.e. installed in my home directory and NOT in /usr/local as root
3. rvm install 1.8.7 and set as default

Now everything seems to be working fine.

My conclusion after days of googling and reading about others’ solutions is that Snow Leopard just doesn’t handle the rails dev environment well unless you sandbox it through RVM in a local director. I resisted going to RVM because I don’t have a need to manage multiple ruby versions.

Some of the responses below along with my code excerpts on pastie may provide some helpful advice for others trying to troubleshoot. In particular from @fl00r and @Kelvin:
run which -a for gem, bundle, rails, rake, etc. to see the available versions. Check to see which versions of ruby are being called with head -1 on each.

Original Below

Pretty much at my wit’s end after a few days of Googling, uninstalling, and re-installing. I’m trying to get rails running on Mac OS X 10.6.7. I followed the Hivelogic Post on this topic. Apologize for the length of this question.

Has anyone followed a step-by-step uninstall/reinstall process for getting this working? Or a link to advice on troubleshooting? Should I clean out everything following this advice from Chad Wooley and migrate to RVM?

The common theme has been errors related to being unable to find gems even though they are installed. For instance, trying to create a new rails app:

kevindewalt@new-host-4:~/Documents$ $ rails new blog
You don't have i18n installed in your application. Please add it to your Gemfile and run bundle install

Or an existing app I have running on another machine after running bundle install:

kevindewalt@new-host-4:~/Documents/ClaimAway$ (master) $ rake db:setup
(in /Users/kevindewalt/Documents/ClaimAway)
Could not find i18n-0.4.2 in any of the sources
Try running `bundle install`.
kevindewalt@new-host-4:~/Documents/ClaimAway$ (master) $ rails s
/usr/local/lib/ruby/gems/1.8/gems/actionpack-3.0.0/lib/action_dispatch.rb:35:in `require': no such file to load --

Answer 1

add to Gemfile

gem 'i18n'

Actually you should specify exact version also:

gem 'i18n', '0.4.2'

then run bundle install. But as far your i18n gem will be locked try this:

bundle update i18n

That is all what is written in your error.
