您在MIDDLEWARE设置中添加了两个无效条目：

'oscar.apps.customer.auth_backends.EmailBackend',
'django.contrib.auth.backends.ModelBackend',

这两个都不是中间件，而是应该添加到AUTHENTICATION_BACKENDS设置的身份验证后端：

AUTHENTICATION_BACKENDS = (
    'oscar.apps.customer.auth_backends.EmailBackend',
    'django.contrib.auth.backends.ModelBackend',
)
