Question

我在RVM上使用Ruby 2.0.0（在FreeBSD 9.1-i386 GENERIC上）做了一个简单的$ gem install cucumber，当我运行$ cucumber时出现以下错误：

uninitialized constant Cucumber::RUBY_1_8_7 (NameError)

Answer 1

在master中删除了中断的代码，请尝试：

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

如果你想以这种方式使用任何额外的宝石，你需要将它们放入Gemfile，你可以阅读更多关于它的信息，并bundler访问它的网站：http://gembundler.com

Answer 2

看起来像Cucumber版本1.3.2中的错误，它应该是相对修复的。

查找cucumber/constantize：

gem which cucumber/constantize

在你的情况下它应该是：

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

编辑此文件并在开头添加此文本：
```
require 'cucumber/platform'
```
