在使用 box bento/centos-7 的新 Vagrant VM 上，以下命令破坏了我的 pip 安装：
yum update
yum install epel-release -y
yum install python-pip -y
/usr/bin/pip2 install --upgrade pip setuptools pyOpenSSL psycopg2-binary lxml
这最终失败了

SyntaxError: invalid …我开始使用 bitbucket CI 制作应用程序，我正在使用以下步骤来部署应用程序，但安装 pip 的步骤失败了。

不知道为什么，但python get-pip.py步骤失败并出现以下错误。

直到昨天，这一切正常。不知道为什么这现在不起作用。
我认为这可能是因为 Windows，但我检查了运行 linux 的本地机器，但这些步骤但它们工作正常。
我想使用与 python 2.7（但不是 3.8）兼容的 python 脚本
我需要 pip 才能使脚本正常工作，但看起来我无法再安装 pip 了？我尝试使用 get-pip.py ，但它不起作用：
user@DESKTOP-J9T7UBF
$ get-pip.py
