我正在寻找一些RHEL6服务器，并试图设置它们以使用内部的PyPi服务器（由Nexus 3代理）。
问题是我们的内部PyPi服务器是同一个Nginx服务器上的几个SSL VHosts之一，Python 2.6不是SNI兼容; 因此，easy_install失败，因为它试图从错误的Vhost URL下载，并且由于SNIMissingWarning和InsecurePlatformWarning而导致pip失败。
我查看了https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings上的build议，但似乎这是您自己的脚本的解决方法; 它不能解决Python本身的问题。 无论如何，我安装了urllib3和相关的软件包，问题仍然存在。
