vue-cli是用来生成 vue项目的命令行工具，它的使用方法是这样的：
vue init <template-name> <project-name>
第二个参数 template-name 就是我们打算使用的模板，目前，模板是通过github上vue-templates这个组织进行发布。我们通常使用的vue init webpack my-project， 其中webpack指的就是 基于webpack的vuejs初始化模板。
本文就根据webpack这套模板（https://github.com/vuejs-templates/webpack/tree/master/template）
进行介绍，基于的版本是#658
首先来到package.json文件里，package.json是npm的配置文件，里面设定了脚本以及项目依赖的库。 npm run dev 这样的命令就写在package.json里。
