vue.js - vue-loader:如何在 webpack 4 和 vue-cli3 中使用 vue-loader v15

Question

我使用最新版本的 vue-cli3 webpack4 和 vue-loader v15。

我想配置vue-loader，但是出现错误:

Error: [VueLoaderPlugin Error] No matching use for vue-loader is found.
Make sure the rule matching .vue files include vue-loader in its use.

vue.config.js

const HtmlWebpackPlugin = require("html-webpack-plugin");
const VueLoaderPlugin = require("vue-loader/lib/plugin");
module.exports = {
    productionSourceMap: false,
    baseUrl: "./",
    configureWebpack: {
        module: {
            rules: [{
                test: /\.vue$/,
                loader: "vue-loader"
            }]
        },
        plugins: [
            new VueLoaderPlugin()
        ]
    }
}

      },

我打了电话 console.log在 vue-loader/plugin.js .
rawRules (第 27 行)

有 20 多个规则。 /\.vue$/符合第二条规则。

但第二条规则是 url-loader？

我该怎么办？

我认为您应该将 vue-loader 放在依赖项上。最近我更新了我的项目:vue、vue-loader、webpack ...
这是我的 package.json

{
  "name": "pack",
  "private": true,
  "version": "0.0.0",
  "scripts": {
    "build": "webpack --env.prod --config webpack.config.js"
  },

    "vuetify": "^1.3.14"
  },
  "browserslist": [
    "> 1%",
    "last 2 versions",
    "not ie <= 8"
  ]
}

你的 webpack.config 看起来不错......但以防万一，这是我的代码:

var path = require('path')
var webpack = require('webpack')
const bundleOutputDir = './wwwroot/dist';
const VueLoaderPlugin = require('vue-loader/lib/plugin')

module.exports = {
  mode: 'development',
  context: __dirname,
  entry: {
    main: ['babel-polyfill', './App/index.js']
  },
  plugins:[
    new VueLoaderPlugin()
  ],
  module: {
    rules: [{
        test: /\.css$/,
        use: [
          'vue-style-loader',
          'css-loader'
        ],
      },
      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: {
          loaders: {
            'scss': [
              'vue-style-loader',
              'css-loader',
              'sass-loader'
            ],
            'sass': [
              'vue-style-loader',
              'css-loader',
              'sass-loader?indentedSyntax'
            ]
          }
        }
      },

...
