什么是urllib3文档告诉我要做什么？

我正在尝试部署Kilo OpenStack Cloud ，我收到此错误：

执行'/ usr / bin / openstack令牌问题 - 格式值'返回1：/usr/lib/python2.7/site-packages/requests/packages/urllib3/util/ssl_.py:90:InsecurePlatformWarning：A true SSLContext对象不可用 . 这可以防止urllib3正确配置SSL，并可能导致某些SSL连接失败 . 有关更多信息，请参阅

所以我去：https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning

我发现我没有访问比2.7.5更好的python版本，所以我看看：

https://urllib3.readthedocs.org/en/latest/security.html#pyopenssl

那么做他们推荐我做的......

# pip install pyopenssl ndg-httpsclient pyasn1
/usr/lib/python2.7/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
  InsecurePlatformWarning

You should consider upgrading via the 'pip install --upgrade pip' command.

文档也说这个：

安装软件包后，您可以告诉urllib3使用inject_into_urllib3（）将ssl后端切换到PyOpenSSL：import urllib3.contrib.pyopenssl urllib3.contrib.pyopenssl.inject_into_urllib3（）现在您可以像往常一样继续使用urllib3 .

我不明白这意味着什么？我需要修补一些python源代码吗？

更新：

我按照Josep的建议做了，这就是发生的事情：

# python
Python 2.7.5 (default, Jun 24 2015, 00:41:19) 
[GCC 4.8.3 20140911 (Red Hat 4.8.3-9)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import urllib3
>>> import pyopenssl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named pyopenssl

然而我安装了pyopenssl ......

# pip install pyopenssl
Requirement already satisfied (use --upgrade to upgrade): pyopenssl in /usr/lib64/python2.7/site-packages

更新：

如果我这样做会发生什么......

# python
