python3全局名稱'SOL_SOCKET未定義

當我使用gevent時，我不能使用requests，是我的用法錯誤嗎？python3全局名稱'SOL_SOCKET未定義

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

它引發錯誤：

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

我的Python的版本是3.3

如果我添加ssl=False到monkey.patch_all()，它返回：

有趣。該名稱將在'ssl'模塊中找到並導入。我看到Python 3.3被支持;你安裝了哪個版本的openssl？ –

@MartijnPieters \t 你的意思是linux包openssl？我的openssl是openssl-1.0.1e-48.el6_8.1.x86_64，CentOS 6.8 – haofly

問題是，顯然'從ssl導入SOL_SOCKET'爲您的安裝失敗。爲什麼這是我不完全理解。也許你在某處有一個影子'ssl'模塊？ 'import ssl;例如，print（ssl .__ file __）'應該打印一個系統位置。 –

這真是一個gevent中的bug。它試圖從ssl庫中導入socket constant。

該特定常數發生將被導入到ssl庫中，因爲該庫使用它。但它只是在那裏，因爲修復issue 19422需要將其導入ssl模塊。該錯誤的修復已包含在Python 3.3.4中，並且您有版本3.3.3，因此您在ssl模塊中也沒有該特定的常量。

您可以通過在gevent/_ssl3.py（位於系統上的/usr/local/lib/python3.3/site-packages目錄中）中添加from socket import SOL_SOCKET, SO_TYPE來修復該問題。或者你可以升級到Python 3.3.4或更新的版本。

我已將此項作爲issue #856與gevent項目一起提交。

安裝Python 3.5版本可以解決這個問題。
