当我尝试使用 rails s

运行服务器时出现问题

我正在使用Windows，这是回报：

Answer 1

尝试将随机数（例如，6532）添加到tmp / pids / server.pid文件中，然后启动webricks

Answer 2

Windows和Rails通常不像其他环境那样有效。最佳解决方法Windows with Rails中的Webbrick问题是安装另一台服务器进行开发。 Mongrel是一个很好的选择。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。我发现最简单的修复方法实际上只是删除应用程序文件夹中的现有pid文件：

del tmp\pids\*.*
