升级Werkzeug至2.0.3后仍遇Flask 'as_tuple'关键字参数错误

错误详情 #

运行API测试时触发如下错误：

if request is None:
>           builder = EnvironBuilder(*args, **kwargs)
E           TypeError: EnvironBuilder.__init__() got an unexpected keyword argument 'as_tuple'

相关测试代码 #

@pytest.fixture(autouse=True)
def client():
    app = my_app()
    with app.test_client() as client:
        yield client

def test_new_func(client, monkeypatch):
    monkeypatch.setattr(UnitPricing, 'find_unit_price', find_unit_pricing)
    monkeypatch.setattr(FullPricing, 'find_full_price', find_full_pricing)

    response = client.post("/price/calc", json=input_payload)
    assert response.status_code == 200
    assert json.loads(response.data) == output_data

已尝试方案及问题 #

此前查到的解决方案建议固定Werkzeug版本为2.0.3，我的requirements.txt已配置该版本，当前环境也确实是Flask 2.0.2 + Werkzeug 2.0.3，但错误依然存在，求解决。
