我必須將應用程序從一臺服務器移至另一臺服務器。這也是Debian的，所以我安裝的安裝舊服務器上的所有Python包，然後將文件移動到同一個目錄（我希望：d）將應用程序移至新服務器
當我嘗試檢查，如果它的工作原理我收到這樣的錯誤：

我不知道我忘了安裝什麼。不幸的是 - 移動之前無法檢查它是否工作（舊服務器關閉）。爲了理解 - 很久以前的應用程序正常工作。相比之下，有一些apt-get dist-upgrade可能會導致此錯誤。今天我想要使用這個應用程序，並且我發現服務器已經定義好了，所以我把所有的東西都搬到了新的地方（幸福的是，HDD仍然有效）。
「TemplateSyntaxError：抓取時配置不正確：'django.db.backends.postgresql'不是可用的數據庫後端。」這似乎很清楚。你安裝了postgres嗎？ – 2011-04-07 16:33:05
您是否安裝了'postgresql'？ http://www.postgresql.org/ – Blender 2011-04-07 16:33:37
@Blender - 當然可以 - 我可以通過settings.py中定義的主機和端口telnet到postgres。 – 2011-04-09 14:39:35
