如何在我的VUE应用程序中全局导入一个scss变量文件？

问题描述

我正在使用webpack的第3版开发新的应用程序，并根据官方webpack文档中的以下文章安装了sass-loader。

https://webpack.js.org/loaders/sass-loader/

这是我的package.json

按照这些步骤，我在webpack.base.config.js中进行了修改，包括在“规则”部分中测试：/.s [ac] ss $ / i

这是我的webpack.base.config.js

'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')

function resolve (dir) {
  return path.join(__dirname,'..',dir)
}



module.exports = {
  context: path.resolve(__dirname,'../'),entry: {
    app: './src/main.js'
  },output: {
    path: config.build.assetsRoot,filename: '[name].js',publicPath: process.env.NODE_ENV === 'production'
      ? config.build.assetsPublicPath
      : config.dev.assetsPublicPath
  },resolve: {
    extensions: ['.js','.vue','.json'],alias: {
      'vue$': 'vue/dist/vue.esm.js','@': resolve('src'),}
  },module: {
    rules: [
      {
        test: /\.vue$/,loader: 'vue-loader',options: vueLoaderConfig
      },{
        test: /\.s[ac]ss$/i,use: [
          // Creates `style` nodes from JS strings
          'style-loader',// Translates CSS into CommonJS
          'css-loader',// Compiles Sass to CSS
          'sass-loader',],},{
        test: /\.js$/,loader: 'babel-loader',include: [resolve('src'),resolve('test'),resolve('node_modules/webpack-dev-server/client')]
      },{
        test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,loader: 'url-loader',options: {
          limit: 10000,name: utils.assetsPath('img/[name].[hash:7].[ext]')
        }
      },{
        test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/,name: utils.assetsPath('media/[name].[hash:7].[ext]')
        }
      },{
        test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
        }
      }
    ]
  },node: {
    // prevent webpack from injecting useless setImmediate polyfill because Vue
    // source contains it (although only uses it if it's native).
    setImmediate: false,// prevent webpack from injecting mocks to Node native modules
    // that does not make sense for the client
    dgram: 'empty',fs: 'empty',net: 'empty',tls: 'empty',child_process: 'empty'
  }
}

但是当我在main.js中导入包含scss变量的文件时，编译失败，提示它找不到我要引用的模块。 在这里，我如何导入_variables.scss

// 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 App from './App'
import router from './router'
import store from './store'
import BootstrapVue from 'bootstrap-vue'
import 'bootstrap/dist/css/bootstrap.min.css'
import 'bootstrap-vue/dist/bootstrap-vue.css'
import axios from 'axios'
import Config from './config.js'
import './styles/_variables.scss'



Vue.config.productionTip = false

Vue.use(BootstrapVue)

axios.defaults.baseURL = Config.BASE_URL_API
axios.defaults.headers.get['Accepts'] = 'application/json'

const reqInterceptor = axios.interceptors.request.use(config => {
  console.log('Request Interceptor',config)
  return config
})
const resInterceptor = axios.interceptors.response.use(res => {
  console.log('Response Interceptor',res)
  return res
})

axios.interceptors.request.eject(reqInterceptor)
axios.interceptors.response.eject(resInterceptor)


/* eslint-disable no-new */
new Vue({
  el: '#app',router,store,components: { App },template: '<App/>'
})

这是我的VSC控制台中的错误：

This relative module was not found:

* ./styles/_variables.scss in ./src/main.js
