Vue 项目安装 scss 以及报错的解决方法

以你之姓@ 2023-07-09 10:25 30阅读 0赞

#### 1. 安装sass依赖 ####

npm install --save-dev sass-loader
    //sass-loader依赖于node-sass
    npm install --save-dev node-sass

### 第一种：Module build failed: TypeError: this.getResolve is not a function ###

###### 如果运行之后项目报错 ######

Module build failed: TypeError: this.getResolve is not a function
        at Object.loader (C:\Users\DELL\Desktop\fantastic-macarons\node_modules\sass-loader\dist\index.js:52:26)
    
     @ ./node_modules/vue-style-loader!./node_modules/css-loader?{ "sourceMap":true}!./node_modules/vue-loader/lib/style-compiler?{ "vue":true,"id":"data-v-469af010","scoped":true,"hasInlineConfig":false}!./node_modules/sass-loader/dist/cjs.js?{ "sourceMap":true}!./node_modules/vue-loader/lib/selector.js?type=styles&index=0!./src/components/HelloWorld.vue 4:14-375 13:3-17:5 14:22-383
     @ ./src/components/HelloWorld.vue
     @ ./src/router/index.js
     @ ./src/main.js
     @ multi (webpack)-dev-server/client?http://localhost:8080 webpack/hot/dev-server ./src/main.js

###### 那是sass-loader 版本太高, 更换成 7.3.1 ######

npm uninstall sass-loader（卸载当前版本）
     npm install sass-loader@7.3.1 --save-dev

###### 在build文件夹下的webpack.base.conf.js的rules里面添加配置 ######

{ 
    	test: /\.scss$/,
    	loaders: ['style', 'css', 'sass']
    }

就可以在别的文件中引用

###### 引入scss文件，使用 ######

@import '../assets/scss/triangle.scss'

###### 不用使用 ######

@import url('../assets/scss/triangle.scss');

会产生报错

### 第二种：Syntax Error: Error: PostCSS received undefined instead of CSS string ###

ERROR  Failed to compile with 1 error7:07:54 ├F10: PM┤
    
     error  in ./src/components/TotalSales/index.vue?vue&type=style&index=0&id=86e7da4a&lang=scss&scoped=true&
    
    Syntax Error: Error: PostCSS received undefined instead of CSS string
    
    
     @ ./node_modules/vue-style-loader??ref--8-oneOf-1-0!./node_modules/css-loader/dist/cjs.js??ref--8-oneOf-1-1!./node_modules/vue-loader/lib/loaders/stylePostLoader.js!./node_modules/postcss-loader/src??ref--8-oneOf-1-2!./node_modules/sass-loader/dist/cjs.js??ref--8-oneOf-1-3!./node_modules/cache-loader/dist/cjs.js??ref--0-0!./node_modules/vue-loader/lib??vue-loader-options!./src/components/TotalSales/index.vue?vue&type=style&index=0&id=86e7da4a&lang=scss&scoped=true& 4:14-478 14:3-18:5 15:22-486

#### 问题原因 ####

node-sass 和 sass-loader 版本与当前的不兼容，安装对应版本的包即可。

#### 解决方案 ####

卸载node-sass 和 sass-loader

npm uninstall node-sass sass-loader

#### 安装对应版本的包 ####

npm install node-sass@4.14.1 sass-loader@8.0.0 --dev

### 第三种：Cannot find module ‘node-sass’ ###

按照往常的思路，应该是 npm install 的时候，出错了。于是我选择重新 npm install node-sass -D,但是安装的时候，报错了

老实说第一次看见这个报错，不明所以，后来上网百度了一下，觉得可能是版本太低了。查看了一下 package.json 的版本号，是 4.4.1 ，抱着试一试的心态，我安装了 最新版本的 `npm install node-sass@latest -D`, 终于安装成功了。
