Question

我正在使用vuetify 1.5版，并将其升级到最新版本2.3.10。当我尝试运行Webpack服务器时，它给了我这个错误。我添加了 yarn add sass -D ，但无法解决此问题。请帮我解决这个问题。

更新1

const { environment } = require('@rails/webpacker')
const coffee =  require('./loaders/coffee');
const vue =  require('./loaders/vue')

environment.loaders.append('coffee', coffee);
environment.loaders.append('vue', vue)
environment.loaders.append('jshint', {
  test: /\.js$/, // include .js files
  enforce: "pre", // preload the jshint loader
  exclude: /node_modules/, // exclude any and all files in the node_modules folder
  use: [{
      loader: "jshint-loader"
  }]
});

environment.loaders.append('signature_pad', {
  test: /\.js?$/,
      include: [/node_modules\/signature_pad/],
  use: [{
    loader: 'babel-loader',
    options: {
      cacheDirectory: true,
      presets: [['env', { 'modules': false, 'targets': { 'node': 4 } }]]
    }
  }],
});

const resolver = {
  resolve: {
    alias: {
      'vue$': 'vue/dist/vue.js'
    }
  }
};
environment.config.merge(resolver);

module.exports = environment;

vue.js

const { dev_server: devServer } = require('@rails/webpacker').config

const isProduction = process.env.NODE_ENV === 'production'
const inDevServer = process.argv.find(v => v.includes('webpack-dev-server'))
const extractCSS = !(inDevServer && (devServer && devServer.hmr)) || isProduction

module.exports = {
  test: /\.vue(\.erb)?$/,
  use: [{
    loader: 'vue-loader',
    options: { extractCSS }
  }]
}

Answer 1

extractCSS会导致这种问题。我会尝试禁用它，如果它可以工作-然后尝试从那时开始对其进行调试。
您的sass-loader版本相对较新。我会尝试将其降级为版本9.0.3。我最近在版本10中遇到了一些问题，可能是您的情况。
我最后看到的-您的配置文件似乎丢失了VueLoaderPlugin。我会将其添加到您的环境文件中，但是我认为这不是问题的根源。

const { VueLoaderPlugin } = require('vue-loader')
// ...
environment.plugins.prepend('VueLoaderPlugin', new VueLoaderPlugin())
environment.loaders.prepend('vue', vue)
// ...
