Question

I already have installed this gem: googlecharts.rubyforge.org, but I don’t want to require it every time I need it on my actions, so I am trying to do it the Rails way:

config.gem 'mattetti-googlecharts'

Then I go and start my server and get this error:

Missing these required gems:
mattetti-googlecharts

You’re running: ruby 1.8.7.174 at
/usr/bin/ruby1.8 rubygems 1.3.5 at
/home/laptop/.gem/ruby/1.8,
/var/lib/gems/1.8

Run rake gems:install to install the
missing gems.

But the gem is installed! I also tried this variant:

config.gem 'mattetti-googlecharts', :lib => 'gcharts'

Answer 1

Use RubyGems repository. The GitHub gem is outdated.

$ gem install googlecharts

Then in your app

config.gem 'googlecharts'

You don’t need to require gchart because of this. Also note, you were trying to require gcharts.rb, not gchart.rb.
