当我尝试运行我的单元测试时，我收到一条错误消息，指出数据库中没有可用的表。一天前我的测试运行良好，围绕我从那时起所做的更改进行的头脑风暴并没有让人想起任何接近导致此问题的东西。

我认为这是一个问题，syncdb并且South没有在数据库中正确创建表sqlite，并试图解决这个问题。

带有回溯的错误消息

没有解决问题的类似 SO 问题

到目前为止我尝试过的

  • 在另一个分支上运行测试，在发生这种情况时没有更改 结果：得到相同的确切错误和引用
  • 吹走我的虚拟环境并开始一个新的
    结果：没有变化

我最终South从我的settings/test.py文件中删除*，并且数据库已正确创建。很想听听是否有人对为什么会发生这种情况有任何想法。下面的设置应该禁用 South，导致 Djangosyncdb创建正确的表。

SOUTH_TESTS_MIGRATE = False  
SOUTH_SKIP_TESTS = True

*我有每个环境的设置文件，所以只需将 South 放在需要它的地方，而不是将它放在base.py它们都继承的地方。
