对于任何 pip install SSL: CERTIFICATE_VERIFY_FAILED 错误

我是 Ubuntu 新手。尝试设置 python（用于 Ansible 控制系统）。作为此设置的一部分，我需要安装 xmltodict 和 markupsafe。我想我缺少一些配置设置部分。

环境#

带有 VirtualBox 的 Windows 10，其上装有 Ubuntu 18.x vbox。pip
--version (pip 9.0.1 来自 /usr/lib/python2.7/dist-packages (python 2.7)

$ pip install xmltodict
No matching distribution found for xmltodict
