为了确保我在当前的 django 项目中正确设置了设置,我执行了以下操作:

  • 向南添加到 installed_apps
  • manage.py syncdb(使用 windows)
  • manage.py convert_to_south 应用

我还没有对我的数据库进行更改,但无论我是否这样做,我都会运行:

  • manage.py schemamigration app --auto

我收到以下错误:

SyntaxError: invalid syntax

这是怎么回事? 它不允许我使用架构迁移。搜索了很多地方并删除和重置数据库以及所有内容,似乎无法找出问题所在。

问题已解决:

不知道 south_migrationhistory 的位置。我一直想知道一些额外的信息挂在哪里。

看看这里:http ://south.aeracode.org/ticket/1069

它是在较新的 South 版本中修复的错误。看来您使用的是 South(<=0.7.3) 的过时版本
