2.命令变化
Commands:
create [options] create a new project powered by vue-cli-service // 创建一个由vue-cli-service支持的新项目
add [pluginOptions] install a plugin and invoke its generator in an already created project // 在已创建的项目中添加插件
invoke [pluginOptions] invoke the generator of a plugin in an already created project // 在开发者模式下以零配置运行一个js或vue文件
inspect [options] [paths...] inspect the webpack config in a project with vue-cli-service // 在vue-cli-service的项目中检查webpack配置
serve [options] [entry] serve a .js or .vue file in development mode with zero config // 简单理解为开发环境下启动命令
build [options] [entry] build a .js or .vue file in production mode with zero config // 在生产模式下以零配置构建一个js或vue文件
init generate a project from a remote template (legacy API, requires @vue/cli-init) // 旧api 需要@vue/cli-init // 就是原来的vue-cli init
3.创建一个项目
新建文件夹，在该文件夹下打开命令窗口，输入以下命令，
vue create project-name
这时你会看见
Vue CLI v3.0.0-beta.6
? Please pick a preset: (Use arrow keys)
> xs-default (vue-router, vuex, stylus, babel, pwa, eslint, unit-jest) // 这是我运行过之后的默认设置，第一次执行create是没有的
default (babel, eslint)
Manually select features
按键盘上下键选择默认（default）还是手动（Manually），如果选择default，一路回车执行下去就行了（注：现在vue-cli3.0默认使用yarn下载），这里我选择手动，

12.装好后，启动
cd vue-pro3.0-demo // 进入项目根目录
yarn serve // 启动项目

13.项目目录，现在的目录是3.0的cli看上去简洁多了，去掉了2.0 build和config等目录

14.修改端口，在根目录下创建vue.config.js

vue.config.js相关配置请参考 https://github.com/vuejs/vue-cli/blob/dev/docs/config.md
在vue.config.js找到
devServer: {
open: process.platform === 'darwin',
host: '0.0.0.0',
port: 1234,
https: false,
hotOnly: false,
// See https://github.com/vuejs/vue-cli/blob/dev/docs/cli-service.md#configuring-proxy
proxy: null, // string | Object
before: app => {}
},
