異常值：“ DatabaseWrapper”對象沒有屬性“ Database”

Question

在輸入此問題之前，我查看了類似的帖子。 我正在使用Django 1.5，Python 3.3.2和MySQL 5.6 / Connector。

我是Django / Python的新手，並逐步學習了基礎教程。 我創建了一個MySQL數據庫，同步了一個非常簡單的模型，並啟動了基本的Web服務器。 我已經通過基本的shell命令將條目添加到表中，並且一切正常。

但是，當我登錄到管理門戶時，它立即引發異常。

當我成功登錄到管理門戶時，在瀏覽器上看到的追溯是：

重新安裝django。 好像您已經在1.4之上安裝了django 1.5
