Capistrano失敗 - 沒有當前目錄/ bundle：未找到/回滾

Question

最近我將其中一個rails應用程序移到了新配置的EC2 ubuntu實例中。運行與舊版服務器相同的ruby版本，apache與乘客。但我仍然無法使用Capistrano將應用程序部署到服務器。仍然我不知道這個錯誤，所以我在這裏粘貼我的部署日誌。另外這裏是我的Capistrano recipe。感謝有人在這裏找到問題。

上面並沒有創造current目錄由於某種原因，但我可以看到releases和shared目錄。加上共享目錄裏面我有一個名爲uploads

總之另一個目錄，它看起來像捆命令沒有在服務器上找到。

您可以確認它是通過SSH'ing安裝到服務器中的'ubuntu'（部署文件中指定的用戶）並嘗試運行bundle。如果您收到命令未找到錯誤，則可能未安裝捆綁器或「ubuntu」用戶沒有權限。

如果上述命令有效，那麼當cap嘗試執行其命令時，您的環境變量可能不會被加載。我必須在部署腳本中指定以下環境變量：

default_environment['PATH'] = '/usr/local/lib/ruby/gems/1.9.1/bin:$PATH' 
default_environment['GEM_PATH']= '/usr/local/lib/ruby/gems/1.9.1' 

顯然，請調整路徑以適合您的服務器的配置。

我希望這有助於！
