rails 服务器不工作，Rails 4.2.0
rails server not working, Rails 4.2.0
我正在按照 Michael Hartl 的 Rails 教程进行操作，在我捆绑安装所有必需的 gem 之后，rails 服务器在我 运行 时给我一个错误。我正在使用 Windows
这是错误：

查看错误，您的开发组中的 web-console gem 似乎是导致问题的原因。一些环顾四周 online，似乎这个特定的 gem 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）。
尝试注释掉 web-console，然后 bundle install、rails c
如果还是不行，请添加：
gem 'rubysl-pty', :platforms => :ruby
gem 'web-console', :platforms => :ruby
然后 bundle install、rails c 如果这能解决您的问题，请告诉我们！
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，并且使用的是 Windows 机器，请尝试安装 Linux/Unix ...
改变
gem 'web-console', '2.0.0.beta3'
到
gem 'web-console', '>= 2.0.0'
应该可以正常工作
