PyTest-Django没有丢失django_migration表

我正在尝试将pytest-django添加到我当前的pytest3/Django1.7环境中.

目前我们还没有使用该插件,并且在某些测试之间一直处于共享状态

一切似乎在视觉上看起来很好,测试似乎通过直到最后我收到以下错误消息:

request = >

    @pytest.fixture(autouse=True)
    def _django_db_marker(request):
        """Implement the django_db marker, internal to pytest-django.

        This will dynamically request the ``db`` or ``transactional_db``
        fixtures as required by the django_db marker.
        """
        marker = request.keywords.get('django_db', None)
        if marker:
            validate_django_db(marker)
            if marker.transaction:
                getfixturevalue(request, 'transactional_db')
            else:
                getfixturevalue(request, 'db')

    def execute(self, query, params=None):
        if params is None:
            return Database.Cursor.execute(self, query)
        query = self.convert_query(query)
>       return Database.Cursor.execute(self, query, params)
E       OperationalError: no such table: django_migrations

ve/lib/python2.7/site-packages/django/db/backends/sqlite3/base.py:485: OperationalError

我试图创建表ensure_schema中conftest.py.我试过的每个选项--nomigrations和--create-db到pytest.

我猜这是遗留系统的一个奇怪的配置问题,但我不知道从哪里开始寻找.有人有建议吗？
