Question

我在PyCharm中调试代码时遇到了一个非常严重的错误。导致异常的违规行是

a = db.links.list_indexes()

或以下：

db.links.create_index("created", expireAfterSeconds=settings.EXPIRY_PERIOD, background=True)

如果我只是run tests，我的代码在PyCharm中正常运行，而尝试调试它会导致以下错误：

我不知道为什么测试在命令行中传递，并且在简单的运行模式下但不在调试模式下。有人可以在这里阐明这个问题吗？

事实证明，该问题确实是组合使用或gevent与调试器一起使用的问题。如果您遇到此问题，可以通过将pycharm版本升级到2006.1来解决。有关详细信息，请参阅issue in PYCharm tracker

Pymongo仅在PyCharm调试器中出错
