python创建虚拟环境

创建一个专门存放站点的目录(虚拟环境)

mkdir  Desktop/Project/virtualenv

创建python3.5的虚拟环境

注意:需要指定python3.5的目录

$ cd  Desktop/Project/virtualenv
$ virtualenv -p /Library/Frameworks/Python.framework/Versions/3.5/bin/python3.5  test

进入虚拟环境

source Desktop/Project/virtualenv/test/bin/activity

进入虚拟环境后查看python版本

注意:直接执行python就OK,pip也是直接执行pip,自动对应的就是python3.5和pip3.5
