POW，OS X - 代理服務器超時 - 502錯誤

Question

我在OSX上運行POW服務RoR應用程序進行開發。幾天前，我的一個應用程序打破了返回502錯誤。頁似乎加載，直到它撞上超時顯示此消息：

Proxy Error 

The proxy server received an invalid response from an upstream server. 
The proxy server could not handle the request GET /index.html. 

Reason: Error reading from remote server 

我檢查日誌，有什麼 - 沒有Ruby代碼是execuded，所以軌道沒有碰到。我在終端輸入導航欄s，應用程序無任何問題。

此外，我通過GIT將我的應用程序恢復到了發行前的階段，甚至到了最初的階段，結果也一樣。

* .dev域中的其他開發應用程序工作正常。

不知道問題在哪裏，我應該在哪裏尋找它。我將不勝感激任何幫助。

Answer 1

已解決。

我不得不在〜/ Library/Logs/Pow/app /中看到日誌，發現Ruby bug。 http://pow.cx/manual.html#section_2.6

我已經降級的Ruby 2.2.2 - > 2.2.1和它的作品。所以我敢打賭是這樣的，對我來說問題是爲什麼在運行rails s時它工作正常。
