运行 npm serve 时获取错误消息模块构建失败(来自 ./node_modules/sass-loader/dist/cjs.js) [英] Getting error message Module build failed (from ./node_modules/sass-loader/dist/cjs.js) when running npm serve

问题描述

我从事 Vue/Vuetify 项目已经有一段时间了.直到昨天一切正常.我在使用 vuetify 组件时遇到了问题，所以我决定运行 npm install 并重新安装 vuetify:坏主意.

I'm working on a Vue/Vuetify project for quite some time now. It all worked fine until yesterday. I had problems with using the <v-simple-table> vuetify component, so I decided to run npm install and re-install vuetify: bad idea.

问题是我在运行 npm run serve 时多次收到以下错误:

The problem is that I get the following error multiple times when running npm run serve:

Module build failed (from ./node_modules/sass-loader/dist/cjs.js):
ValidationError: Invalid options object. Sass Loader has been initialised using an options object that does not match the API schema.
 - options has an unknown property 'indentedSyntax'. These properties are valid:
   object { implementation?, sassOptions?, prependData?, sourceMap?, webpackImporter? }

我的 main.js 文件:

My main.js file:

import Vue from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'

import Vuetify from 'vuetify/lib'
import 'vuetify/dist/vuetify.min.css'
import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue/dist/bootstrap-vue.css'

Vue.use(BootstrapVue)
Vue.use(Vuetify, {
  theme: {
    "primary": "#FFCA28",
    "secondary": "#1976D2",
    "accent": "#82B1FF",
    "error": "#FF5252",
    "info": "#2196F3",
    "success": "#4CAF50",
    "warning": "#FB8C00"
  }
})

Vue.config.productionTip = false

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

我已经看过很多帖子了，他们都建议运行 npm rebuild node-sass(都在管理模式下定期运行)，删除 node-modules 文件夹，重新安装 sass-loader，但到目前为止没有任何效果.

I've already looked at multiple posts and they all advise to run npm rebuild node-sass (both regularly as in admin-mode), delete the node-modules folder, re-install sass-loader, but nothing worked so far.

我的 main.js 可能有问题吗?

Is there something wrong in my main.js maybe?

提前致谢！如果我需要发布更多代码或其他信息，请告诉我.

Thanks in advance! Let me know if I need to post more of my code or additional information.

推荐答案

这可能是将 sass-loader 从 v7.x 升级到 v8.x 的结果

This could be result of upgrading sass-loader from v7.x to v8.x

如发行说明所述，它们v 对配置进行了重大更改

As stated in release notes, they'v made significant changes to configuration

检查你的 vue.config.js - 如果你发现这样的东西:

Check your vue.config.js - if you find something like this:

module.exports = {
  css: {
    loaderOptions: {
      sass: {
        ....some options here...
      }
    }
  }
}

改为:

module.exports = {
  css: {
    loaderOptions: {
      sass: {
        sassOptions: {
          ....some options here...
        }
      }
    }
  }
}
