[Rspec Load Error] `require': cannot load such file -- engtagger (LoadError)

[cbarraford]

I'm seeing a weird issue with treat and rspec.

I have treat installed and ran the ruby command to install the jar files and other dependencies. That succeeded without an issue. I am using the latest stable version of rvm. When i go into irb i can load engtagger no problem.

2.1.3 :001 > require 'pp'
 => true
2.1.3 :002 > pp Gem.path
["/Users/cbarraford/.rvm/gems/ruby-2.1.3@svo-dev",
 "/Users/cbarraford/.rvm/gems/ruby-2.1.3@global"]
 => ["/Users/cbarraford/.rvm/gems/ruby-2.1.3@svo-dev", "/Users/cbarraford/.rvm/gems/ruby-2.1.3@global"]
2.1.3 :003 > require 'engtagger'
 => true

And i can load it no issue when I run a ruby script.

#!/usr/bin/env ruby

require 'engtagger'
puts "success!"

bash$ ruby proof.rb
success!

But when i load engtagger (and other treat dependency gems) inside an rspec file, i get a load error.

require 'spec_helper'
require 'pp'
pp Gem.path
require 'engtagger'

Has anyone seen this? I'm running the latest version rspec, treat, and ruby.

It looks like this may not be a treat specific problem. If i install a random gem,

gem install thor

Rspec can't load that one either.

But if anyone has any ideas on what I can try to fix it, it would be appreciated.

[cbarraford]

Ah ha! The reason why rspec wasn't able to load some gems is because the gem (ie engtagger) wasn't listed in the gemfile. The treat gem was listed, but because engtagger is a dependency of treat and its not listed as dependency in the gemspec file, rspec didn't know that it was going to need it.

Is there a reason why the treat gemspec doesn't list all of the dependencies??

The reason why we don't list all dependencies is because many of them are C extensions and will fail to install on certain platforms. Another reason is to keep from installing 40 dependencies when a user may only use one or two of them. Therefore, the preferred way is to add these gems to your gemfile.
