1、首先升级
pip install -U pip setuptools

2、查看环境，在使用pip install时，要知道究竟用的那个pip，在PATH、shell 配置和操作系统等里设置都会影响到pip的使用

最好的办法是使用 -m pipwhere是指定安装路径的Python 来调用 pip。例如，用的是python3，则运行python3 -m pip 包名

python3 -m pip install virtualenvwrapper

如果在服务器上运行python3 -m pip install 时提示权限错误，可以 --用户 添加有权限的用户去安装，例如，python3 -m pip install --user …，把包安装到指定用户下，并使当前操作用户可去执行使用。
安装成功则如下：

[root@www Python-3.7.3]# python3 -m pip install virtualenvwrapper
