我的环境是这样的：

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

问题一：

Reverting to Ruby lexer.

这种错误，查询了一下google group邮件组的issues，发现是cucumber的一个bug，在Windows 64位系统上会出现，目前消除这种问题的方式是：找到../gems/gherkin-*.*.*/lib/gherkin/c_lexer.rb文件的第七行，修改prefix = ''，避免提示这种错误。

问题二：

按照正常的编写feature文件和step definition，却一直提示步骤未定义。

我之前使用的命令是到当前目录下执行cucumber test.feature，发现不行。改用cucumber cucumberdemo/test.feature -r cucumberdemo 才能执行。这个问题暂时先记着，回来找到原因我再补充。

问题三：

总是提示：cannot load such file -- spec/expectations (LoadError)

这个是因为rspec-expectations在3.0版本以上修改了运行的逻辑，需要在env.rb中把require 'spec/expectations' 修改成 require 'rspec' 才行。
