Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-llKUfF/distro/
You are using pip version 8.1.2, however version 22.3.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

一般出现这个问题是由于pip版本太低或者pip有问题的原因

sudo yum remove python-pip #先卸载安装的python-pip
wget https://bootstrap.pypa.io/pip/2.7/get-pip.py # 下载get-pip.py文件
sudo python get-pip.py
