我最近从我的 Windows 机器上安装了 ruby 和 rubyonrails.当我使用 rails new FirstApp 创建一个新的 rails 项目时，它工作正常，但是当我尝试使用 rails s 启动 rails 服务器时，它会引发我下面提到的错误:

谁能帮我理解这里的问题以及如何解决它?我正在使用 ruby 2.0.0p195 (2013-05-14) [i386-mingw32] 和 Rails 4.1.0.beta1

解决方案

终于解决了这个问题.确保在 tzinfo-data 条目之前将 gem 'tzinfo' 添加到您的 Gemfile 中，一切都会开始工作.参考:https://github.com/rails/rails/issues/13553>

I recently fromatted my Windows machine and installed ruby and rubyonrails. When I create a new rails project using rails new FirstApp it works fine, but when I try to start the rails server using rails s it throws me the below mentioned error:

Can anyone help me understand the problem here and how to resolve it? I am using ruby 2.0.0p195 (2013-05-14) [i386-mingw32] and Rails 4.1.0.beta1

解决方案

Finally, got rid of the issue. Make sure to add gem 'tzinfo' to your Gemfile before the tzinfo-data entry and everything will start working. Ref: https://github.com/rails/rails/issues/13553
