我的環境是這樣的：
RubyGems Environment: - RUBYGEMS VERSION: 2.0.14 - RUBY VERSION: 2.0.0 (2014-11-13 patchlevel 598) [x64-mingw32] - INSTALLATION DIRECTORY: D:/ruby-2.0.0/lib/ruby/gems/2.0.0 - RUBY EXECUTABLE: D:/ruby-2.0.0/bin/ruby.exe - EXECUTABLE DIRECTORY: D:/ruby-2.0.0/bin - RUBYGEMS PLATFORMS: - ruby - x64-mingw32

問題一：

這種錯誤，查詢了一下google group郵件組的issues，發現是cucumber的一個bug，在Windows 64位系統上會出現，目前消除這種問題的方式是：找到../gems/gherkin-*.*.*/lib/gherkin/c_lexer.rb檔案的第七行，修改prefix = ''，避擴音示這種錯誤。
問題二：
按照正常的編寫feature檔案和step definition，卻一直提示步驟未定義。
我之前使用的命令是到當前目錄下執行cucumber test.feature，發現不行。改用cucumber cucumberdemo/test.feature -r cucumberdemo 才能執行。這個問題暫時先記著，回來找到原因我再補充。
問題三：
總是提示：cannot load such file -- spec/expectations (LoadError)
這個是因為rspec-expectations在3.0版本以上修改了執行的邏輯，需要在env.rb中把require 'spec/expectations' 修改成 require 'rspec' 才行。
