Luffy项目

一、导入项目依赖

为什么导出项目依赖：

本地开发环境和项目上线依赖的环境不相同，所以需要导出项目依赖

如何导出项目依赖：

导出项目依赖的方法有两种，第一种是自己手动编写，第二种是使用插件

# 使用插件生成项目依赖
	- 生成：pip freeze  # 显示当前环境安装的所以依赖
    	pip freeze > requirements.txt  # 将当前项目依赖生成一个txt文本
        
	- 安装依赖
    	pip install -r requirements.txt   # 上线环境环境
		pip install -r dev.txt   # 开发环境

二、前端主页功能

# 首页页面组件
# 头部组件(小组件)
# 轮播图组件(小组件)
# 尾部组件(小组件)
