错误“无法加载此类文件 – 2.0 / Console_ext”在RubyMine中运行unit testing
我正在尝试开始在rails应用程序上运行样本ruby的unit testing，但每当我尝试运行unit testing时，RubyMine就会打印出以下错误
我在运行bundle install时也遇到了同样的错误，因为我在我的Gemfile中添加了gem "win32console", '1.3.0' 。 这是文本forms的错误

导致此错误的原因是什么？如何解决？
使用Ruby 2.0时，您不需要win32console。 Windows上的Ruby 2.0支持ANSI转义序列，正确支持unicode字符输出。 所以win32console gem是不必要的。 去掉它。
另外win32Console是一个古老的gem – 认为它们不支持Ruby 2.0
我的解决方案是简单地在我的Gemfile中注释掉对win32console的引用。 感谢您之前的回答，指出了这一点。
在这种情况下，我的错误是：c：/RailsInstaller/Ruby2.0.0/lib/ruby/gems/2.0.0/gems/win32console-1.3.2-x86-mingw32/lib/Win32/Console.rb:12:in `require’：无法加载这样的文件 – 2.0 / Console_ext（LoadError）
这允许测试运行以及捆绑安装。 长期我可能会删除参考。
