什么是pipenv
- pipenv是requests作者的一个项目, 整合了virtualenv, pip, pipfile, 用于更方便地为项目建立虚拟环境并管理虚拟环境中的第三方模块.
- 虚拟环境可以隔离各种python项目所需要的不同的环境，可以利用python2和python3分别创建虚拟环境，同时运行python2,3的项目
环境：
- python3.6.4
- win10
安装pipenv
- 启动win10终端，命令行输入
pip install pipenv,过程大概需要一两分钟，具体网络情况而定 - 安装完成显示：
-

给项目安装虚拟环境
- 进入项目目录下面（
安装pipenv的时候是在全局安装，此时安装项目虚拟环境需要到你的项目目录下面安装） - 输入命令：
pipenv install - 安装完成后显示：
-

激活虚拟环境
- 输入命令：
pipenv shell（退出命令：exit） - 一两秒后完成显示：
-
Launching subshell in virtual environment. Type 'exit' to return. Microsoft Windows [版本 10.0.16299.309] (c) 2017 Microsoft Corporation。保留所有权利。 - 激活之后就可以在虚拟环境里面搭建项目所需要的环境，安装各种包了，下面以flask为例
安装flask
- 进入虚拟环境之后，输入命令：
pipenv install flask - 过程大概十秒左右，完成后显示：
-

flask命令查看是否安装成功，或者输入pip list查看该虚拟环境下所有安装的包
pipenv 常用命令：
- pipenv shell 激活虚拟环境
- exit 退出虚拟环境
- pipenv install *** 安装包
- pipenv uninstall *** 卸载包
- pipenv graph 查看安装包的依赖关系
- pipenv --venv 查看虚拟环境安装目录
- 更过的命令可以查看
