我是django的新手，能帮我解决这个问题吗？

Answer 1

我也遇到过这个问题。我正在看PyCharm Django guide。我通过删除我的sqlite数据库文件并再次运行syncdb修复了这个问题。我不知道为什么它第一次不起作用，但现在它起作用了。

此外，为了查看SQLite数据库的实际结构，下载SQLite Database Browser可能是值得的。对于这个问题，您对django_site表很感兴趣。删除数据库文件并重新运行syncdb后，此表中有一行。

Answer 2

出现这个问题的原因是，第一次执行python manage.py syncdb.时没有指定主用户。要解决此问题，请删除数据库中由django创建的所有表(使用mysql、postgresql..)或者删除database.db (使用sqlite3)，然后再次运行python manage.py syncdb
