Vuetify/Vue-CLI 编译问题;收到换行符错误

Question

在过去的几个小时里，我一直在互联网上搜索答案。我快要疯了。

我有一个新的 Vue 项目，我从vue-cli开始，并添加了 Vuetify。当我运行yarn serve时，我收到一百个错误抱怨：

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

我尝试升级/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？

主.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 有自己的sass-loader配置(并且已经在做你配置的事情(，所以你为sass-loader添加的规则是添加一个重复的处理器，其中 Vue CLIsass-loader的输出被馈送到你的处理器中，导致错误。解决方案是删除您的配置以进行module.rules。

请注意，您还在resolve.extensions中复制了 Vue CLI 配置。我建议使用vue inspect查看项目已解决的 Webpack 配置以进行故障排除。在进行更改之前和之后比较输出很有帮助。
