centos7使用pip安装软件时报错

今天在使用pip安装docker-compose时出现了如下报错

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-6AEQQu/pycparser/

然后按照下边的方法更新安装插件，试了下，成功。

# python -m pip install --upgrade --force pip  
# pip install setuptools==33.1.1
# pip install docker-compose

              .......
