我正在尝试开始为示例 ruby on rails 应用程序运行单元测试，但是每当我尝试运行单元测试时，RubyMine 都会打印出以下错误
自从我将 gem "win32console", '1.3.0' 添加到我的 Gemfile 后，我在运行 bundle install 时也遇到了同样的错误。这是文本形式的错误
Exception message: cannot load such file -- 2.0/Console_ext

此错误的原因是什么，我该如何解决？
最佳答案
使用 Ruby 2.0 时不需要 win32console。 Ruby 2.0 on windows 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。将其删除。
win32Console 也是一个古老的 gem - 认为它们不支持 Ruby 2.0
关于ruby - 在 RubyMine 中运行单元测试时出现错误 "cannot load such file -- 2.0/Console_ext"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/18905821/
