I’ve frozen all the gems used for testing my rails app into vendor/gems  
but some of the dependent gems are loaded from

Do I need to specify each gem in cucumber’s dependency tree in the  
environment initializer?

config/environments/.rb

Right now I only use config.gem to specify these:

cucumber, webrat, rspec, and rspec-rails

Here are all the others cucumber depends on:

$ RAILS\_ENV=test rake gems

…

- [F] cucumber \>= 0.4.2
  - [F] term-ansicolor = 1.0.4
  - [F] treetop = 1.4.2
    - [F] polyglot \>= 0.2.5

  - [F] polyglot = 0.2.9
  - [F] builder = 2.1.2
  - [F] diff-lcs = 1.1.2

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

So treetop is there but running:

$ rake features --trace

results in this error:

undefined method `has\_terminal?’ for  
#Cucumber::Parser::I18n::EnglishParser (NoMethodError)

Presumably because cucumber is using an older gem version of treetop in  
my system gem directory instead of  
vendor/gems/treetop-1.4.2.

Part of the trace:

(eval):23:in `_nt_feature' /Library/Ruby/Gems/1.8/gems/treetop-1.2.5/lib/treetop/runtime/compiled_parser.rb:18:in`send’  
/Library/Ruby/Gems/1.8/gems/treetop-1.2.5/lib/treetop/runtime/compiled\_parser.rb:18:in  
`parse' /Users/stephen/dev/test/rites/vendor/gems/cucumber-0.4.2/bin/../lib/cucumber/parser/treetop_ext.rb:28:in`parse\_or\_fail’

I’m guessing you’ve run into an issue where Cucumber is calling  
“require ‘treetop’” before the Rails stack is initialized (and thus  
before vendor/gems is loaded as a gem source). Adding treetop to your  
config.gem stuff may not help, but a full stack trace from both  
conditions (with config.gem ‘treetop’ and without) will be helpful.

Don’t do that. Only deployment gems should go in there. Testing gems  
should just be specified in config/environments/test.rb , as recommended  
(I think) in the RSpec and Cucumber docs.
