GRequests猴贴片警告

Question

每次我都会收到以下警告，尽管模块按预期工作：

/usr/local/lib/python3.7/site-packages/grequests.py:21: MonkeyPatchWarning: Monkey-patching ssl after ssl has already been imported may lead to errors, including RecursionError on Python 3.6. It may also silently lead to incorrect behaviour on Python 3.7. Please monkey-patch earlier. See https://github.com/gevent/gevent/issues/1016. Modules that had direct imports (NOT patched): ['urllib3.util (/usr/local/lib/python3.7/site-packages/urllib3/util/__init__.py)', 'urllib3.contrib.pyopenssl (/usr/local/lib/python3.7/site-packages/urllib3/contrib/pyopenssl.py)']. 
  curious_george.patch_all(thread=False, select=False)

我尝试了在这个github问题上提到的解决方法，但这不起作用。

如何消除这个警告？

Answer 1

对于grequests，在其他模块尝试导入/加载gevent和ssl之前，您需要添加以下代码：

from gevent import monkey as curious_george
curious_george.patch_all(thread=False, select=False)

Answer 2

请参阅grequests：https://github.com/spyoungtech/grequests

好：

import grequests 

import requests

坏：

import grequests
