如果在Centos版的云服务器上，用pip安装包的时候出现“WARNING: Running pip as the ‘root’ user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv” 这样的话，请尝试一下这种方式解决：

命令行依次执行：

1 export PIP_ROOT_USER_ACTION=ignore

2 pip install –root-user-action=ignore requests

3 pip install –upgrade pip

4 pip install xxxxx
