我$ gem install cucumber用 Ruby 2.0.0（在 FreeBSD 9.1-i386 GENERIC 上）在 RVM 上做了一个简单的操作，当我运行时$ cucumber出现以下错误：

中断的代码已在 master 中删除，请尝试：

bundle init # create a Gemfile
echo "gem 'cucumber', :git => 'https://github.com/cucumber/cucumber.git'"
bundle install
bundle exec cucumber

如果您想以这种方式使用任何额外的宝石，您需要将它们放入Gemfile您可以阅读更多信息并bundler访问它的网站： http: //gembundler.com

貌似是Cucumber版本的bug 1.3.2，应该是相对修复的。

  1. 查找cucumber/constantize：

    gem which cucumber/constantize

    在您的情况下，它应该是：

    /home/black/.rvm/gems/ruby-2.0.0-p0@cucumber/gems/cucumber-1.3.2/lib/cucumber/constantize.rb

  2. 编辑此文件并在开头添加此文本：

    require 'cucumber/platform'
