OP

@megachweng 这是代码
import pytest

def test_main():
assert 5!=5

if __name__ == "__main__":
pytest.main()

下面是报错提示：
[Running] python -u "d:\MyPytest\test_sample.py"
Traceback (most recent call last):
File "d:\MyPytest\test_sample.py", line 1, in <module>
import pytest
ModuleNotFoundError: No module named 'pytest'

[Done] exited with code=1 in 0.185 seconds

在命令行是可以正常执行得
