如何使用 Webpack 3 配置 Ant Design

Question

修复和解决方案：

感谢@BoyWithSilver，长话短说，这是我为解决问题所做的工作：

将 .less 添加到扩展部分
删除了 webpack.config.json 中不必要的代码，例如删除了 extract-text-webpack-plugin
从 3.0.1 降级到 2.7.0 修复了一堆错误：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
已添加

启用javascript：真在 webpack.config.json

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"
        })
      },]
  }
};

现在错误消息变为：

ERROR in multi (webpack)-dev-server/client?http://localhost:8080 ./src/index.js Module not found: Error: Can't resolve './src/index.js' in '/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

下有 index.js

我正在尝试集成支持较少的 Ant Design 和此处的按需导入功能： https://ant.design/docs/react/use-with-create-react-app 在高级指南部分。

本节中使用了react-app-rewired，但我的项目使用的是webpack 3（我的项目是基于此https://github.com/mobxjs/mobx-react-boilerplate），所以在我的例子中不能使用rewired命令。

于是我又找到了一篇文章： 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"

 ]

}

以下是来自控制台的错误消息：

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 = {

Ant主题变量配置(ant-theme-vars.less):

  @primary-color: #4099ff;
  @font-size-base: 16px;
  @font-family : "Proxima Nova", Helvetica Neue, Helvetica, Arial, sans-serif;
  @btn-font-size-lg: 15px;
  @btn-padding-lg : 8px 32px;
  @btn-padding-sm : 4px 16px;

Answer 2

错误似乎是由于无法解析 .less 文件所致。将此添加到 webpack.config.js 应该有助于解决它们：

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

您已将上下文指定为结构中的 src 文件夹。这意味着必须将条目更改为 ./index.js 或只是 ./index 如果您不想拥有 context 密钥，删除它也可以完成工作。

Answer 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

Answer 4

我刚刚将该导入语句添加到我的 index.scss 文件中，然后警告消失了

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

Answer 5

React 解决方案：

在 index.js 文件夹中

导入'antd/dist/antd.css

替换为

导入'antd/dist/antd.min.css
