无法运行Rails服务器

Question

我尝试使用rails运行服务器时遇到问题

我正在使用Windows，这是返回值：

C:\Blog\MyBlog>rails s

我尝试使用杂种，但我在cmd中得到了下一个：

Answer 1

尝试在tmp / pids / server.pid文件中添加一个随机编号（例如6532），然后启动webricks

Answer 2

Windows和Rails通常无法在其他环境中正常工作。 带有Rails的Windows中，Webbrick的最佳解决方法是安装另一台服务器进行开发。 杂种是一个很好的选择。 要安装它：

gem install mongrel

然后启动服务器

rails s mongrel

Answer 3

我遇到了同样的问题。 我发现最简单的解决方法实际上是删除应用程序文件夹中的现有pid文件：

del tmp\pids\*.*
