I Your application is running here: http://localhost:8080
注意：
如果浏览器打开之后，没有加载出页面，有可能是本地的 8080 端口被占用，需要修改一下配置文件 config里的index.js 的 post
module.exports = {
dev: {
// Paths
assetsSubDirectory: 'static',
assetsPublicPath: '/',
proxyTable: {}, // 这里可以配置跨域
// Various Dev Server settings
host: 'localhost', // can be overwritten by process.env.HOST
port: 8080, // 端口 就是改这里
autoOpenBrowser: false, // 这里是ture的话，就会自动打开浏览器。
我的端口没有被占用，所以直接启动成功，打开 http://localhost:8080 就能看到欢迎页面。
vue-cli 的 webpack 配置分析
从 package.json 可以看到 开发 和 生产 环境的入口。
"scripts": {
"dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js",
"start": "npm run dev",
"test": "npm run unit",
"lint": "eslint --ext .js,.vue src test/unit",
"build": "node build/build.js"
},
dev 就是开发环境的启动命令
build 是生产打包环境的命令
lint 是ESLint的检查命令 在 --ext 前加一个 --fix 可以自动修复不符合规范的代码
打包上线：
运行 npm run build 命令，就可以进行打包工作了，打包完成后，会生成 dist 目录，项目上线时，把dist 目录下的文件放到服务器就可以了。
调试工具 vue-tool
在谷歌商店，搜索这个插件，安装到浏览器，调试项目很好用。
另：
1.npm 开启了npm run dev以后怎么退出或关闭？
ctrl+c
2.--save-dev
自动把模块和版本号添加到模块配置文件package.json中的依赖里devdependencies部分
3. --save-dev 与 --save 的区别
--save 安装包信息将加入到dependencies（生产阶段的依赖）
--save-dev 安装包信息将加入到devDependencies（开发阶段的依赖），所以开发阶段一般使用它.
