Django-1.3 beta的問題

Question

家伙！ 我非常熱衷於學習django並在Django-1.2上學到了一點但是我安裝了1.3版本，直到我使用命令“python manage.py runserver”運行服務器。 它給出了一個巨大的錯誤。 我無法找到解決這個問題的方法。 錯誤如下：

Traceback (most recent call last):

Answer 1

如果您安裝了兩個版本，則會發生這種情況。 刪除django（/usr/local/lib/python2.6/dist-packages/django）只需刪除整個文件夾即可。 現在重新安裝Django 1.3，它應該工作。

為避免將來出現此類問題，請使用virtualenv
