目前，我在 Ubuntu 14.04 上运行 vagrant 服务器，并使用简单的python manage.py runserver 0.0.0.0:8000

由于我使用 chrome through 连接到 django 网络服务器http://localhost:8000并且服务器在 VM 上运行，因此我通过使用以下设置进行端口转发Vagrantfile

config.vm.network "forwarded_port", guest: 8000, host: 8000

一切正常运行（所有模块/视图/测试都按预期运行），但是，自从我开始使用以来，grequests我得到了这个奇怪的错误

Exception happened during processing of request from ('10.0.2.2', 63520)
Traceback (most recent call last):
  File "/home/vagrant/anaconda3/lib/python3.6/socketserver.py", line 639, in process_request_thread

    result = waiter.get()

    return self.hub.switch()

    return RawGreenlet.switch(self)
gevent.hub.LoopExit: ('This operation would block forever', <Hub at 0x7f3b777e8af8 epoll pending=0 ref=0 fileno=34>)

请注意，我没有使用，并且即使没有调用它或其他任何东西grequests，简单地导入它似乎也会导致此错误

有人有想法么？

这是底层依赖项之一的问题 - gevent，它覆盖了 python 内置的默认行为，例如time等。

你将不得不猴子补丁。就像是：

from gevent import monkey
monkey.patch_all()

这是相关gevent文档。

我最近遇到了这个确切的问题 - 所以停止使用grequests并实现我自己的异步请求逻辑
