Question

I am a bit confused over what is happening. I have my application using a few different gems and for some reason there is a problem requiring any more gems. So for example. I have this in config/environment.rb

config.gem 'will_paginate', :version => '2.3.12'
config.gem "bandsintown"
config.gem "gchartrb"

I just added gchartrb. When i run

 rake gems
(in /Users/matt/Sites/someapp)
  - [R] will_paginate = 2.3.12
  - [R] bandsintown 
  - [ ] gchartrb 

 I = Installed
 F = Frozen
 R = Framework (loaded before rails starts)

then i run

sudo rake gems:install

gem install gchartrb
Successfully installed gchartrb-0.8
1 gem installed

gem list | grep gchart
gchartrb (0.8)

So I am confused on what to do. I am on snow leopard on mac osx. Here is my environment

which gem
 /usr/local/bin/gem
which ruby
 /usr/local/bin/ruby

gem env

If anyone has any clue to why I cant seem to install any other gems into this application…

here is my error

script/server 
=> Booting WEBrick
=> Rails 2.3.8 application starting on http://0.0.0.0:3000
Missing these required gems:
  gchartrb  

You're running:
  ruby 1.8.7.174 at /usr/local/bin/ruby
  rubygems 1.3.7 at /Users/matt/.gem/ruby/1.8, /usr/local/lib/ruby/gems/1.8

Run `rake gems:install` to install the missing gems.

The problem here is that gchartrb is the name of the gem, but you need to require google_chart to load the gem. Try this instead

config.gem "gchartrb", :lib => "google_chart"
