我正在尝试部署 Kilo OpenStack 云，但出现此错误：
'/usr/bin/openstack token issue --format value' 的执行返回 1: /usr/lib/python2.7/site-packages/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext 对象不可用。这会阻止 urllib3 正确配置 SSL，并可能导致某些 SSL 连接失败。有关详细信息，请参阅
所以我去： https ://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning
我发现我无法访问比 2.7.5 更好的 python 版本，所以我查看：
https://urllib3.readthedocs.org/en/latest/security.html#pyopenssl
所以做他们建议我做的事情......
# 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 are using pip version 7.1.0, however version 7.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

文档也这样说：
安装软件包后，您可以使用 inject_into_urllib3() 告诉 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。
我不明白那是什么意思？是否有一些我需要修补的python源代码？
更新：
我按照 Josep 的建议做了，这就是正在发生的事情：
# 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
然而我已经安装了 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...
