python - Pytest E DeprecationWarning : defusedxml. lxml 不再受支持，将在未来版本中删除

Question

我有一个简单的Python代码，如下所示:

文件名:test_pytest_openpyxl.py

import openpyxl

def test_1():
    print("test_1")

if __name__ == "__main__":
    test_1()

python test_pytest_openpyxl.py

它通过了，没有错误。然而，

pytest test_pytest_openpyxl.py 出现以下错误:
