神祕的錯誤使用帶有grequests

Question

目前，我在Ubuntu 14.04上運行的流浪漢服務器Django的服務器時，我通過使用簡單的python manage.py runserver 0.0.0.0:8000

測試所有我的Django的模塊，因爲我連接到Django的web服務器使用Chrome通過http://localhost:8000且服務器上虛擬機上運行，​​我是通過以下設置的使用端口轉發在Vagrantfile

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

一切運行正常（所有模塊/視圖/測試功能如預期），但是，自從我開始使用grequests我得到這個奇怪的錯誤，我沒有使用grequests和簡單地導入似乎引起即使不被稱之爲這個錯誤

Exception happened during processing of request from ('10.0.2.2', 63520)

注或任何東西

任何人有任何想法？

這是與底層依賴性的一個問題 - gevent，它覆蓋內建如time蟒蛇的默認行爲等

你將不得不猴補丁。 喜歡的東西：

from gevent import monkey 
monkey.patch_all() 

下面是相關gevent documentation。

我最近就遇到了這個問題的確切 - 使用grequests所以就停並實現我自己的異步請求邏輯
