Question

当我使用gevent时，我无法使用requests，我的用法是错误的吗？

from gevent import monkey; monkey.patch_all()
import gevent, requests
requests.get('https://haofly.net')

它引发了错误：

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.3/site-packages/requests/api.py", line 70, in get
  return request('get', url, params=params, **kwargs)

我的Python版本是3.3

如果我将ssl=False添加到monkey.patch_all()，则会返回：

Answer 1

这是gevent中的一个错误。它正在尝试从ssl库中导入socket constant。

将特定常量发生导入ssl库，因为该库使用它。但它只是因为issue 19422的修复程序需要将其导入ssl模块。该错误的修复程序包含在Python 3.3.4中，并且您具有版本3.3.3，因此您在ssl模块中也没有可用的特定常量。

您可以通过在from socket import SOL_SOCKET, SO_TYPE（位于系统的gevent/_ssl3.py目录中）添加/usr/local/lib/python3.3/site-packages来解决此问题。或者您可以升级到Python 3.3.4或更高版本。

我已将issue #856与gevent项目一起提交。

Answer 2

安装Python 3.5版本可以解决这个问题。

python3全局名称＆＃39; SOL_SOCKET未定义
