Question

过去几个小时，我一直在互联网上寻找答案。我要疯了。

我有一个新的Vue项目，我从vue-cli开始，并添加了Vuetify。运行yarn serve时，出现一百个错误，抱怨：

 ERROR  Failed to compile with 100 errors                                                                   2:02:26 PM

我尝试了升级/降级sass-loader，删除node-sass和各种Webpack配置（通过vue.config.js）。有人有解决方案吗？

main.js

import Vue from 'vue';
import vueHeadful from 'vue-headful';
import vuetify from './plugins/vuetify';

import App from './App.vue';
import router from './router';
import store from './store/index';

Vue.config.productionTip = false;

Vue.component('vue-headful', vueHeadful);

new Vue({
  router,
  store,
  vuetify,
  render: h => h(App),
}).$mount('#app');

vuetify.js

import Vue from 'vue';
import Vuetify from 'vuetify/lib';
import Unicon from 'vue-unicons';
import { uniCarWash } from 'vue-unicons/src/icons';

Vue.use(Vuetify);

Unicon.add([uniCarWash]);
Vue.use(Unicon);

export default new Vuetify({
  icons: {
    iconfont: 'uni',
  },
});

vue.config.js

const path = require('path');

module.exports = {
  transpileDependencies: [
    'vuetify',
  ],
  css: {
    loaderOptions: {
      sass: {
        data: `@import "~/scss/variables.scss"`,
      },
    },
  },
  chainWebpack: config => {
    ["vue-modules", "vue", "normal-modules", "normal"].forEach(match => {
      config.module.rule('scss').oneOf(match).use('sass-loader')
        .tap(opt => Object.assign(opt, { data: `@import '~@/scss/variables.scss';` }));
    });
  },
  configureWebpack: {
    resolve: {
      alias: {
        '~': path.resolve(__dirname, './src/'),
      },
      extensions: ['*', '.js', '.vue', '.json'],
    },
    module: {
      rules: [
        {
          test: /\.s(c|a)ss$/,
          use: [
            'vue-style-loader',
            'css-loader',
            {
              loader: 'sass-loader',
              options: {
                implementation: require('sass'),
                fiber: require('fibers'),
              },
            },
          ],
        },
      ],
    },
  },
};

Vue CLI对sass-loader有自己的配置（并且已经在做您配置的事情），因此您为sass-loader添加的规则是添加一个重复的处理器，其中输出Vue CLI的sass-loader被输入到您的Vue CLI中，从而导致错误。解决方案是删除module.rules的配置。

请注意，您还要在resolve.extensions中复制Vue CLI配置。我建议使用vue inspect查看项目的已解析Webpack配置以进行故障排除。在进行更改之前和之后对输出进行比较很有帮助。

Vuetify / Vue-CLI问题编译；收到换行错误
