用RubyMine进行debug的时候，启动时出现异常_Ruby_编程开发_程序员俱乐部

Rails环境：

Rails版本v2.2.2

Ruby版本1.8.7

ruby-debug (0.10.4)
ruby-debug-base (0.10.5.jb2 mswin32)
ruby-debug-ide (0.4.16)

今天用rubymine3.1的debug功能进行调试的时候，发现启动的时候发现了异常，没有找到原因，希望路过的大侠们帮忙解决一下

启动信息：

?

找到原因了，上面是RubyMine中的异常信息，因为中文显示乱码，所以很难定位到出错的地方，我在命令行窗口又启动了一下debug

ruby scripy/server -u

错误信息：

这个信息就很明显知道哪里出了问题了，启动服务器以后没有关闭，直接进行了debug，端口冲突导致的
