我有仍在运行 Python 2.7.6 的旧生产服务器。我们有一个从 ubuntu 14.04 的 docker 镜像构建的本地环境，旨在复制该环境（安装完所有内容后，一切仍然可以正常工作。）创建此环境的打包器构建脚本最近显然停止工作，因为 PyPi 放弃了非 SNI 支持。
我尝试使用get-pip.py文档下载 pip：
wget -c https://bootstrap.pypa.io/pip/2.7/get-pip.py
python2 get-pip.py
这给了我以下警告：
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021.
