我很难完成迄今为止在过去一年没有问题的任务。在我的机器上开发我的Ruby Padrino应用程序。我会用流浪汉。一旦流浪起来，我加载putty中的设置并执行“bundle exec padrino start -h 0.0.0.0”。这通常会导致环境负荷但是重新启动我的电脑后，我现在收到此错误：软件包的问题exec exec padrino start
RuntimeError: Rack config file `0.0.0.0` must have `.ru` extension

我也不得不运行包安装此所以我想知道它是一个更新的宝石文件造成这个问题还是其他什么东西之前， 。任何信息，将不胜感激。
