Vue框架搭建

时间:2022-09-29 奔跑吧邓邓子人气:0

一、安装 NodeJS

二、安装 vue-cli

1.vue-cli 2.x 升级到 3.x

（1）卸载 2.x 版本

npm uninstall -g vue-cli

（2）安装

npm install -g @vue/cli

（3）查看版本

vue -V

vue -V@vue/cli 5.0.8

三、创建项目

1.vue-cli 2.x 项目

（1）创建

vue init webpack test2.0

D:\test>vue init webpack test2.0
? Project name test2.0
? Project description A Vue.js project
? Author chaoyue <chaoyue@qq.com>
? Vue build standalone
? Install vue-router? Yes
? Use ESLint to lint your code? Yes
? Pick an ESLint preset Standard
? Set up unit tests No
? Setup e2e tests with Nightwatch? No
? Should we run `npm install` for you after the project has been created? (recommended) yarn

   vue-cli · Generated "test2.0".

# Project initialization finished!
# ========================

To get started:

  cd test2.0
  npm run dev

Documentation can be found at https://vuejs-templates.github.io/webpack

创建完成后，项目目录结构如下：

在这里插入图片描述

（2）启动

cd test2.0
npm install
npm run dev

在这里插入图片描述

（3）安装 vux ①不使用模板安装

npm install vux --save
npm install vux-loader --save-dev
npm install less less-loader --save-dev

修改 build\webpack.base.conf.js ：

const vuxLoader = require('vux-loader')

const originalConfig = {
...

const webpackConfig = originalConfig // 原来的 module.exports 代码赋值给变量 webpackConfig

module.exports = vuxLoader.merge(webpackConfig, {
  plugins: ['vux-ui']
})

src 下创建 views 目录，新建 test.vue 文件：

<template>
  <div style="padding: 15px;">
    <button-tab>
      <button-tab-item selected>{{ today }}</button-tab-item>
      <button-tab-item>{{ week }}</button-tab-item>
      <button-tab-item>{{ month }}</button-tab-item>
    </button-tab>
  </div>
</template>

<script>
  import {ButtonTab, ButtonTabItem} from 'vux'
  export default {
    components: {
      ButtonTab,
      ButtonTabItem
    },
    data () {
      return {
        today: '今天',
        week: '本周',
        month: '本月'
      }
    }
  }
</script>

<style scoped>

</style>

配置路由 router\index.js ：

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Test from '@/views/test'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/',
      name: 'HelloWorld',
      component: HelloWorld
    },
    {
      path: '/test',
      name: 'test',
      component: Test
    }
  ]
})

访问 http://localhost:8080/#/test ：

常见错误：
1.Module build failed: TypeError: this.getOptions is not a function
解决方法：
less 和 less-loader 版本过高，安装低版本：

npm install less@3.9.0 less-loader@4.1.0 --save-dev

2.You may use special comments to disable some warnings.
Use // eslint-disable-next-line to ignore the next line.
Use /* eslint-disable */ to ignore all warnings in a file.
解决方法：
原因是开启了 eslint 编码规范检查，修改 build\webpack.base.conf.js ，注释掉以下一行代码：

//...(config.dev.useEslint ? [createLintingRule()] : []),

②使用模板安装

vue init airyland/vux2 test-t2.0

D:\test>vue init airyland/vux2 test-t2.0
? Project name test-t2.0
? Project description A Vue.js project
? Author chaoyue <chaoyue@qq.com>
? Vue build standalone
? Install vue-router? Yes
? Use ESLint to lint your code? Yes
? Pick an ESLint preset Standard
? Setup unit tests No
? Setup e2e tests with Nightwatch? No
   vue-cli · Generated "test-t2.0".
   To get started:
     cd test-t2.0
     npm install
     npm run dev
   Documentation can be found at https://vuejs-templates.github.io/webpack

官网模板的路由是以常量的形式写在 main.js 中，我们改造到 router/index.js 中去：
修改 main.js：

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import FastClick from 'fastclick'
import router from './router'
// import VueRouter from 'vue-router'
import App from './App'
// import Home from './components/HelloFromVux'
//
// Vue.use(VueRouter)
//
// const routes = [{
//   path: '/',
//   component: Home
// }]
//
// const router = new VueRouter({
//   routes
// })

FastClick.attach(document.body)

Vue.config.productionTip = false

/* eslint-disable no-new */
new Vue({
  router,
  render: h => h(App)
}).$mount('#app-box')

修改 index.js：

import Vue from 'vue'
import Router from 'vue-router'
// import HelloWorld from '@/components/HelloWorld'
import Hello from '@/components/HelloFromVux'
import Test from '@/views/test'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/',
      name: 'Hello',
      component: Hello
    },
    {
      path: '/test',
      name: 'test',
      component: Test
    }
  ]
})

启动：

cd test-t2.0
npm install
npm run dev

访问 http://localhost:8080/
