1. Mac系统默认是没有安坟装pip安装工具，在终端运行以下命令

sudo  easy-install pip

2. 设定环境变量：

vi ~/.bash_profile

export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Devel
source /usr/local/bin/virtualenvwrapper.sh
退出保存
3.执行生效
source ~/.bash_profile

4.测试创建目录

JazzdeMacBook-Air:~ jazzli$ mkvirtualenv testdir

 

5.查看创建的虚拟环境目录

JazzdeMacBook-Air:~ jazzli$ workon

testdir
