【问题描述】：

我正在使用 python 2.7.6、Django 1.8 和 python-social-auth。尝试通过 googleoauth2 进行身份验证时出现此错误。回溯已附加。这些我都试过了-

sudo apt-get install ca-certificates
sudo apt-get install ntpdate

但即使那样它也不起作用。

【问题讨论】：

我有同样的问题正在运行 - django 1.9 - python 2.7.6 - certifi 2016.2.28 - requests 2.9.1 它从一周前开始运行良好。任何解决它的想法都会很好。谢谢，沃尔特
同样的问题，运行 Django==1.9.4，requests-oauthlib==0.6.1，requests==2.10.0，certifi==2016.2.28。而且我的网站没有 ssl 证书。有人找到解决方法或知道问题所在吗？

【解决方案1】：

pip2.7 install --upgrade httplib2

上述解决方案对我有用

【解决方案2】：

我遇到了同样的问题。尝试做pip install urllib3[secure]，urllib3 默认没有证书，所以你必须这样做。这也显示在这里 --> https://urllib3.readthedocs.org/en/latest/security.html#security

【解决方案3】：

你可以安装以下包

python -m pip install  pyopenssl pyasn1 ndg-httpsclient

我通过安装上述库解决了同样的问题。

您在这里安装了 3 个库，而不仅仅是一个。能解释一下为什么要重新安装它们吗？
