Pytest更新后未连接到数据库

Question

Pytest因Attrs库而被迫更新后抛出大量错误

每个测试都有

之类的错误

ERROR             [  3%]Creating test database for alias 'default' ('test_dev')...

test setup failed
self = <django.contrib.gis.db.backends.postgis.base.DatabaseWrapper object at 0x108a614d0>

    def ensure_connection(self):
        """Guarantee that a connection to the database is established."""
        if self.connection is None:
            with self.wrap_database_errors:
>               self.connect()

venv/lib/python3.7/site-packages/django/db/backends/base/base.py:216: 

测试代码如下

def test_user_registration(client):
    url = reverse('auth-register')
    credentials = {
        'email': 'test@test.com',
        'password': 'localhost',
        'username': 'test@test.com',
        'firstName': 'Jane',
        'lastName': 'Doe'
    }
    response = client.json.post(url, json.dumps(credentials))
    assert response.status_code == 201
    expected_keys = ['jwt', 'user']
    user_expected_keys = [
        'confirmed', 'blocked', '_id', 'email', 'username', 'firstName',
        'lastName', 'role', 'createdAt', 'updatedAt', 'readarticles', 'id',
        'property'
    ]
    assert set(expected_keys) == response.data.keys()
    assert set(user_expected_keys) == response.data['user'].keys()

这是完整的跟踪信息，似乎是姿势连接上的错误，我确保数据库已启动，并且服务器运行没有任何问题= Pytes版本是5.0.0-让我知道还有什么要发表的内容
