修复和解决方案：

感谢@BoyWithSilver，长话短说，这是我解决问题的方法：

在扩展部分添加了 .less
删除了 webpack.config.json 中不必要的代码，例如删除了 extract-text-webpack-plugin
将 less 从 3.0.1 降级到 2.7.0 修复错误堆：antd 中 index.less 文件中未定义的长度。

更新 3

这是我的 package.json

}

更新 2：

删除上下文选项后： // 上下文：path.resolve(__dirname, 'dist'), 在webpage.config.js中
添加

javascript启用：真在 webpack.config.json 中的 less-loader 下

我收到了这些错误。

更新 1：

这是我的 webpack.config.json

var path = require('path');
var webpack = require('webpack');
const fs  = require('fs');

const ExtractTextPlugin = require("extract-text-webpack-plugin");
const lessToJs = require('less-vars-to-js');
const themeVariables = lessToJs(fs.readFileSync(path.join(__dirname, './scripts/ant-theme-vars.less'), 'utf8'));

module.exports = {
  watch: true,
  context: path.resolve(__dirname, './src'),
  devtool: 'source-map',
  entry: [
    './src/index.js'
  ],
  output: {
    path: path.resolve(__dirname, './dist'),
    filename: '[name].bundle.js'
  },
  plugins: [
    new webpack.HotModuleReplacementPlugin(),
    new ExtractTextPlugin('style.css')
  ],
  resolve: {
    extensions: ['.js', '.jsx']
  },
  module: {
    rules: [{
      test: /\.jsx?$/,
      use: ['babel-loader'],
      include: path.join(__dirname, 'src')
    },
      {
        test: /\.less$/,
        use: ExtractTextPlugin.extract([
          {loader: "css-loader"},
          {loader: "less-loader",
            options: {
              modifyVars: themeVariables,
              root: path.resolve(__dirname, './')
            }
          }
        ])
      },
      {
        test: /\.css$/,
        use: ExtractTextPlugin.extract({
          use: "css-loader"
        })
      },]
  }
};

现在错误信息变为：

多 (webpack)-dev-server/client 中的错误？http://localhost:8080 ./src/index.js 未找到模块：错误：无法解析“./src/index.js” 在'/Users/Winston/tmp/Playground/mobx-reactjsx/src'@multi (webpack)-dev-server/client?http://localhost:8080./src/index.js

（项目结构）

我在 projectfolder/src 下确实有 index.js

我正在尝试将 Ant Design 与 Less 支持和按需导入功能集成在一起： https://ant.design/docs/react/use-with-create-react-app 在高级指南部分。

在本节中，它使用 react-app-rewired 但我的项目使用 webpack 3（我的项目基于此 https://github.com/mobxjs/mobx-react-boilerplate），因此在我的情况下不能使用 rewired 命令。

于是又找了一篇文章： https://medium.com/@GeoffMiller/how-to-customize-ant-design-with-react-webpack-the-missing-guide-c6430f2db10f

这是我的代码：

package.json

"start": "webpack-dev-server --hot --open",

webpack.config.json

const fs  = require('fs');

const lessToJs = require('less-vars-to-js');
const themeVariables = lessToJs(fs.readFileSync(path.join(__dirname, './scripts/ant-theme-vars.less'), 'utf8'));
....
module:{
.....
rules:[
.....
test: /\.less$/,

use: [

       {loader: "style-loader"},

       {loader: "css-loader"},

       {loader: "less-loader",

options: {

modifyVars: themeVariables

         }

       }

     ]
]
}

index.js

import {Button} from 'antd';

<Button type="primary">Hi!</Button>

.babelrc

{

"presets": [

"react",

"es2015",

"stage-1"

 ],

"plugins": [

   ["import", {"libraryName": "antd", "style": true} ],

"transform-decorators-legacy"

 ]

}

这是来自控制台的错误消息：

您面临的问题是什么？
@BoyWithSilverWings 忘记上传错误信息 >_
加载器似乎没有解析.less文件。尝试将resolve: {extensions: ['.js', '.jsx', '.less']}, 添加到 webpack.config.js 文件中
@BoyWithSilverWings 谢谢老兄，它解决了一个，另一个出现了。

【解决方案1】：

Webpack 配置（webpack.config.js）：

const path = require('path');
const webpack = require('webpack');
const ExtractTextPlugin = require("extract-text-webpack-plugin");
const fs  = require('fs');
const lessToJs = require('less-vars-to-js');
const themeVariables = lessToJs(fs.readFileSync(path.join(__dirname, 'ant-theme-vars.less'), 'utf8'));
module.exports = {
  watch: true,
  context: path.resolve(__dirname, './src'),
  entry: {
    app: './index.js',
  },  
  output: {
    path: path.resolve(__dirname, './dist'),
    filename: '[name].bundle.js',
  },
  devtool: 'source-map',
  resolve: {
    alias: {
      moment: 'moment/src/moment'
    },
  },
  module: {
    rules: [
      {
        test: /.jsx?$/,
        loader: 'babel-loader',
        exclude: /node_modules/,
        query: {
          presets: ['env','react','stage-2']
        }
      },
      {
        loader: 'babel-loader',
        exclude: /node_modules/,
        test: /\.js$/,
        options: {
          presets: ['env','react','stage-2'],
          plugins: [
            ['import', { libraryName: "antd", style: true }]
          ]
        },
      },
      {
      test: /\.scss?$/,
        loader: ExtractTextPlugin.extract({
          fallback: 'style-loader',
          loader: 'css-loader!sass-loader'
        })
      },
      {
        test: /\.less$/,
        use: ExtractTextPlugin.extract([
          {loader: "css-loader"},
          {loader: "less-loader",
            options: {
              modifyVars: themeVariables,
              root: path.resolve(__dirname, './')
            }
          }
        ])
      },
      {
        test: /\.(woff|woff2|eot|ttf|otf|svg|png|jpg,pdf)$/,
        loader: "file-loader"
      },
      {
        test: /\.css$/,
        use: ExtractTextPlugin.extract({
          fallback: "style-loader",
          use: "css-loader"
        })
      },
    ]
  },
  plugins: [
    new ExtractTextPlugin('style.css')
  ],
  devServer: {
    port: 9000,
    contentBase: 'dist'
  }
};

还有 package.json：

【讨论】：

感谢 Sivadass，我已经更新了我的 webpack.config.json 并且出现了新的错误消息。请看我的更新1。
@Sivadass N，你能帮忙吗stackoverflow.com/questions/66453633/…

【解决方案2】：

错误似乎来自无法解析.less 文件。将此添加到 webpack.config.js 应该有助于解决它们：

resolve: {
  extensions: ['.js', '.jsx', '.less']
},

您已在结构中将上下文指定为src 文件夹。这意味着必须将条目更改为 ./index.js 或只是 ./index 如果您不是有意拥有 context 密钥，则删除它也可以完成工作。

【讨论】：

谢谢大佬，解决了一个，又出现了一个。请查看我的更新 1 图片了解我的项目结构。
@Franva 您使用的less 是什么版本？
嗨，这是 ^3.0.1。我在更新 3 部分中添加了我的 package.json
@Franva 将其降到 2.7.0 并再次检查
现在就去做。我还需要降级我的less-loader吗？如果是，是什么版本？

【解决方案3】：

对我来说，我只需要使用import 'antd/dist/antd.min.css 而不是import 'antd/dist/antd.css

https://github.com/ant-design/ant-design/issues/33327#issuecomment-997355323

【解决方案4】：

我刚刚将该 import 语句添加到我的 index.scss 文件中，然后警告消失了

@import "antd/dist/antd.css";
