在Django 1.7中運行python manage.py syncdb時出現錯誤

我正在使用Python2.7，但在Python 3.4.3中得到了完全相同的錯誤

$ python manage.py syncdb

Answer 1

我可以看到您正在使用django-CMS，遇到了同樣的問題。 我可以假設較新版本的Django可能存在問題。

根本原因是尚未創建Django表，但cms嘗試引用它們（特別是從Sites框架獲取當前站點）

那不是以前版本的Django中的問題，因為您通常會執行python manage.py sycndb （至少在Django 1.9中已刪除），並且該命令創建了所有django表。

因此，要解決此問題-您需要在settings.py注釋掉與django CMS相關的所有內容，運行python manage.py migrate來遷移Django表，然后取消注釋cms的內容並再次遷移，那么這應該不是問題不再。 （有時，它還有助於注釋已安裝的應用程序中的當前項目以及cms內容，以便Django 1.9進行檢查不會檢查您的urls.py，其中包含與cms相關的條目）。

如果您在Django <1.9但> 1.7上遇到相同的問題，請嘗試首先執行syncdb。

希望對遇到類似問題的任何人有所幫助。

Answer 2

如果尚不存在，請將以下內容添加到settings.py中的INSTALLED_APPS屬性：

'django.contrib.sites'

並在settings.py中也添加SITE_ID = 1 。

在Django 1.7+中，進行數據庫更改的首選方法是使用migration management命令：

./manage.py migrate

那應該解決您的問題。
