Question

I'm using MacPorts in order to manage my Ruby/Rails/Gems installations. Recently after doing a gem install wirble, wirble fails to load when I start an instance of irb. Here's the output:

$ irb --simple-prompt
Couldn't load Wirble: no such file to load -- wirble

The Wirble gem doesn't show up in my $LOAD_PATH:

The gem is definitely installed:

$ gem list |grep -i wirble
wirble (0.1.3)

It is located in /opt/local/lib/ruby/gems/1.9.1/gems/wirble-0.1.3/

How do I get this and future gems I installed appended to my $LOAD_PATH?

Was it helpful?

Solution

I got this to work!

Used this version: https://github.com/blackwinter/wirble.git and it worked!

Hope that helps!

OTHER TIPS

Did you require RubyGems in irb?

require 'rubygems'

will probably be necessary before requiring any gems. You can also put this line in ~/.irbrc so you RubyGems will automatically be required when irb is started up.

I'm not sure why some of your Gems are in your load path -- gems usually don't appear in $:.
