Question

我试图实现https://github.com/pytest-dev/pytest/issues/2039中提到的pytest插件，基本上这个插件会打印pytest发现的所有测试：

## pytest_collector.py
import sys
import pytest

class DkPytestCollector(object):

    def __init__(self):
        self.collected = []

    def pytest_collection_modifyitems(self, items):
        for item in items:
            self.collected.append(item.nodeid)

if __name__ == '__main__':
    dkpytest_collector = DkPytestCollector()
    directory = sys.argv[1]
    pytest.main(['--collect-only', directory], plugins=[dkpytest_collector])

    print('\n\nfound:')
    for nodeid in dkpytest_collector.collected:
        print(nodeid)

但是，当我运行它时，我得到：

如果我pip uninstall pytest-cov一切正常（好吧，除了没有报道......）

如何在不卸载pytest-cov的情况下使其工作？

实现一个简单的pytest插件时没有名为misc的模块？
