我正在遵循Michael Hartl的Rails教程，在我捆绑安装所有必需的gems之后，Rails服务器在运行时给了我一个错误。我正在使用视窗
这是错误：

非常感谢所有帮助
查看错误，似乎开发组中的web-console gem 导致了问题。有些人在网上四处寻找，似乎这个特殊的宝石在Windows环境中不能很好地工作（可以说，Rails作为一个整体在Windows机器上不合作）。
尝试注释掉web-console，然后bundle install ，rails c
如果仍然没有运气，请添加：
gem 'rubysl-pty', :platforms => :ruby
gem 'web-console', :platforms => :ruby
然后bundle install，rails c，让我们知道这是否解决了您的问题！
或者，我建议使用 cloud9，或者如果您想在 rails 应用程序上本地工作，并且正在使用 Windows 机器，请尝试安装 Linux/Unix...
更改
gem 'web-console', '2.0.0.beta3'
自
gem 'web-console', '>= 2.0.0'
应该让它工作
