目前，我在 Ubuntu 14.04 上运行一个 vagrant 服务器，我使用简单的 python manage.py runserver 0.0.0.0:8000 测试我所有的 django 模块。
因为我通过 http://localhost:8000 使用 chrome 连接到 django 网络服务器并且服务器在 VM 上运行，我通过使用 Vagrantfile 中的以下设置进行端口转发
config.vm.network "forwarded_port", guest: 8000, host: 8000
一切正常运行(所有模块/ View /测试都按预期运行)，但是，自从我开始使用 grequests我收到这个奇怪的错误
Exception happened during processing of request from ('10.0.2.2', 63520)
Traceback (most recent call last):

请注意，我没有使用 grequests并且简单地导入它似乎会导致这个错误，即使它没有被调用或任何东西
有人有什么想法吗？
请您参考如下方法:
这是底层依赖项之一 - gevent 的问题，它覆盖了 python 内置的默认行为，例如 time 等。
你将不得不使用 monkeypatch。 像这样的东西:
from gevent import monkey
monkey.patch_all()
这里是相关的gevent documentation .
我最近遇到了这个问题 - 所以停止使用 grequests 并实现了我自己的异步请求逻辑
