关于旧版本

Vue CLI 的包名称由 vue-cli 改成了 @vue/cli。 如果你已经全局安装了旧版本的 vue-cli (1.x 或 2.x)，你需要先>通过 npm uninstall vue-cli -g 或 yarn global remove vue-cli 卸载它。

#一、安装

npm install -g @vue/cli

#二、检查版本

vue --version

#三、初始化项目

🎉  Successfully created project hello-world.
👉  Get started with the following commands:

 $ cd hello-world
 $ npm run serve

#四、运行

cd hello-world

npm run serve

浏览器访问：http://localhost:8080/ (opens new window)，效果如下：

五、项目目录

相比于2.0，文件目录结构简洁不少，少的部分都是一些配置文件，那么以前的配置我们想自定义配置怎么办呢？

五、自定义配置

1、在项目根目录下创建vue.config.js文件

2、vue.config.js基本常用配置（其他的具体看文档 (opens new window)）

module.exports = {
  devServer: {
    port: 8888, // 端口号
    host: 'localhost',
    https: false,
    open: false // 配置是否自动启动浏览器
  }
}
