django:来自 django.contrib.auth 的测试失败

Question

当我运行我的 django 测试时，我得到以下错误，这些错误不在我的测试套件中:

谁能解释一下，我做错了什么或者我应该设置什么才能通过这些测试？

Answer 1

我通过执行以下操作成功地重现了您看到的测试结果:

MIDDLEWARE_CLASSES = (
    'django.middleware.cache.UpdateCacheMiddleware',
    .... <your middleware classes> ....
    'django.middleware.cache.FetchFromCacheMiddleware',
)

如果您有这些行，请尝试删除它们并重新运行单元测试。但是，我对此没有解决方案。
