Topic: uninitialized constant ActionView::Helpers::TagHelper::ERB (NameError)
Hello, I am new to ruby and trying to refactor some ruby code that just consists of a few files containing a couple of small classes and am running rspec on a specification file like "rspec collector_specs.rb" and am getting the following error output:
C:/Ruby191/lib/ruby/gems/1.9.1/gems/actionpack-3.0.3/lib/action_view/helpers/tag_helper.rb:10:in `<module:TagHelper>': u

require 'rubygems'
require 'action_view/helpers/asset_tag_helper'
require 'action_view/helpers/tag_helper'
require 'erb'
class Collector
include ActionView::Helpers::TagHelper
include ActionView::Helpers::AssetTagHelper
def self.foo
"foo"
end
def display(profile, size, html = {}, options = {}, link = true)
... unrelated code here ...
return image_tag("default.png")
end
endI am just starting out with ruby programming and have a lot to learn, so any and all help and input is most appreciated.
