可以在Vue 3项目中安装sass-loader

Question

I am trying to add sass/scss loader AFTER creating a project with vue CLI. I ran this script: $ npm install -D sass-loader@^10 sass and I am receiving following error:

npm ERR! notsup Unsupported platform for fsevents@2.3.1: wanted {"os":"darwin"} (current: {"os":"linux","arch":"x64"})
npm ERR! notsup Valid OS:    darwin
npm ERR! notsup Valid Arch:  undefined
npm ERR! notsup Actual OS:   linux
npm ERR! notsup Actual Arch: x64

It worked for me in empty project that i created to test this. But in my project does not work. I am using Ubuntu 20.04 this is my package.json file:

Answer 1

try deleting your package-lock.json file and node_modules folder and then installing your dependencies again

rm -r node_modules package.json
npm i

Answer 2

Yes you can. add following dependecis in your package.json and run npm i.

"devDependencies": {
    "sass-loader": "^7.2.0",
    "sass": "^1.22.10",
  }

for add global variables you need to make vue.config.js in root directory if not exist. then add your scss varibale file.

module.exports = {
 
  css: {
    loaderOptions: {
      sass: {
        additionalData: '@import "@/assets/styles/file.scss";',
        implementation: require('node-sass')
      },
    },
  },

};
