报错：pytest: error: argument -m: expected one argument (via addopts config)

错误：ERROR: usage: pytest options file_or_dir file_or_dir ...

pytest: error: argument -m: expected one argument (via addopts config)

原因：pytest.ini里面-m应该去掉，因为没指定标签。

[pytest]
markers=
        smoke:冒烟测试
        system:系统测试
addopts=-v -s -m
testpaths=../pytest_test

应改为

[pytest]

addopts=-v -s
