我很難完成迄今爲止在過去一年沒有問題的任務。在我的機器上開發我的Ruby Padrino應用程序。我會用流浪漢。一旦流浪起來，我加載putty中的設置並執行「bundle exec padrino start -h 0.0.0.0」。這通常會導致環境負荷但是重新啓動我的電腦後，我現在收到此錯誤：軟件包的問題exec exec padrino start
RuntimeError: Rack config file `0.0.0.0` must have `.ru` extension

我也不得不運行包安裝此所以我想知道它是一個更新的寶石文件造成這個問題還是其他什麼東西之前， 。任何信息，將不勝感激。
