传统方式

直接下载 vue.min.js，然后通过 script 标签引入。

使用 CDN 方法

以下推荐国外比较稳定的两个 CDN，国内还没发现哪一家比较好，目前还是建议下载到本地。

Staticfile CDN（国内） : https://cdn.staticfile.org/vue/2.2.2/vue.min.js

unpkg：https://unpkg.com/vue/dist/vue.js, 会保持和 npm 发布的最新的版本一致。

cdnjs : https://cdnjs.cloudflare.com/ajax/libs/vue/2.1.8/vue.min.js

NPM 方法

构建大型的前端应用时使用。

$   npm install vue

这个实际上会在本地下载一些文件。

我们稍后会被这些文件进行详细讲解。

cnpm 安装

发现 npm 在国内访问比较慢，这里推荐使用淘宝 NPM 镜像。

淘宝 NPM 镜像是一个完整 npmjs.org 镜像，你可以用此代替官方版本(只读)，同步频率目前为 10分钟一次以保证尽量与官方服务同步。

你可以使用淘宝定制的 cnpm (gzip 压缩支持) 命令行工具代替默认的 npm:

安装命令

$   npm install -g cnpm --registry=https://registry.npm.taobao.org

日志

λ npm install -g cnpm --registry=https://registry.npm.taobao.org
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
C:\Users\Administrator\AppData\Roaming\npm\cnpm -> C:\Users\Administrator\AppData\Roaming\npm\node_modules\cnpm\bin\cnpm

+ cnpm@6.1.1
added 684 packages from 964 contributors in 36.97s

使用

这样就可以使用 cnpm 命令来安装模块了：

$ cnpm install [name]

更多信息可以查阅：http://npm.taobao.org/。

命令行工具

Vue.js 提供一个官方命令行工具，可用于快速搭建大型单页应用。

全局安装 vue-cli

$ cnpm install --global vue-cli
