vue.js 3.2.20:安装使用scss/sass(sass-loader@10.2.0)

一，安装scss/sass:

1,安装插件:

liuhongdi@lhdpc:/data/vue/scssdemo$ vue add style-resources-loader
 
📦  Installing vue-cli-plugin-style-resources-loader...
 
 
added 1 package in 5s
 
14 packages are looking for funding
  run `npm fund` for details
✔  Successfully installed plugin: vue-cli-plugin-style-resources-loader
 
? CSS Pre-processor? (Use arrow keys)
❯ SCSS
  SASS
  Stylus
  Less
 
在询问CSS Pre-processor处选择默认的SCSS并回车

2，为项目安装sass等第三方库支持:

liuhongdi@lhdpc:/data/vue/scssdemo$ npm install -D sass-loader@10.2.0 node-sass sass
 
added 99 packages in 3m
 
14 packages are looking for funding
  run `npm fund` for details

说明：sass-loader如果不指定一个较低的版本，

默认安装高版本时会报冲突

sass-loader选择10这个版本是为了对webpack版本的兼容:

查看当前项目的webpack版本:

iuhongdi@lhdpc:/data/vue/scssdemo$ npm list webpack
scssdemo@0.1.0 /data/vue/scssdemo
├─┬ @vue/cli-plugin-babel@4.5.13
│ ├─┬ babel-loader@8.2.2
│ │ └── webpack@4.46.0 deduped
│ ├─┬ cache-loader@4.1.0
│ │ └── webpack@4.46.0 deduped
│ ├─┬ thread-loader@2.1.3
│ │ └── webpack@4.46.0 deduped
│ └── webpack@4.46.0
...

3,安装完成后查看安装的第三方库:

liuhongdi@lhdpc:/data/vue/scssdemo$ npm list sass-loader
scssdemo@0.1.0 /data/vue/scssdemo
└── sass-loader@10.2.0
 
liuhongdi@lhdpc:/data/vue/scssdemo$ npm list sass
scssdemo@0.1.0 /data/vue/scssdemo
├─┬ sass-loader@10.2.0
│ └── sass@1.42.1 deduped
└── sass@1.42.1
 
liuhongdi@lhdpc:/data/vue/scssdemo$ npm list node-sass
scssdemo@0.1.0 /data/vue/scssdemo
├── node-sass@6.0.1
└─┬ sass-loader@10.2.0
  └── node-sass@6.0.1 deduped

查看package.json

"dependencies": {
    "core-js": "^3.6.5",
    "vue": "^3.0.0"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "~4.5.0",
    "@vue/cli-plugin-eslint": "~4.5.0",
    "@vue/cli-service": "~4.5.0",
    "@vue/compiler-sfc": "^3.0.0",
    "babel-eslint": "^10.1.0",
    "eslint": "^6.7.2",

    "node-sass": "^6.0.1",
    "sass": "^1.42.1",
    "sass-loader": "^10.2.0"
  },

二，编写代码：

 Home.vue

<template>
<div class="main" style="">
  <div class="top">
  <span @click="changeColor('red')" >红色</span>
  <span @click="changeColor('yellow')" >黄色</span>
  <span @click="changeColor('blue')" >蓝色</span>
  <span @click="changeColor('green')" >绿色</span>
    </div>
  <div class="demo">
  </div>
</div>
</template>

<script>
export default {
  name: "Home",
  setup() {
    const changeColor = (color) => {
      document.getElementsByTagName('body')[0].style.setProperty('--div_bg', color);
    };
    return {
      changeColor,
    }
  },
}
</script>

<style lang="scss" scoped>
/*$bg: red;*/
$bg: var(--div_bg, #ff0000);

.main {
   width:100vw;
   height:100vh;
   background: #eeeeee;
   .top {
     margin-top: 0px;
     width:500px;
     height:30px;
     span {
       margin-top: 10px;
       float: left;
       margin-left: 30px;
       background: #2c3e50;
       border-radius: 5px;
       color: #ffffff;
       width:50px;
       height: 30px;
       line-height: 30px;
     }
   }

  .demo {
    width:100px;
    height:100px;
    margin-top: 20px;
    margin-left: 30px;
    border-radius: 10px;
    background-color: $bg;
  }
}
</style>

liuhongdi@lhdpc:/data/vue/scssdemo$ npm list vue
scssdemo@0.1.0 /data/vue/scssdemo
