create-react-app与antd一起使用The "injectBabelPlugin" helper has been deprecated as of v2.0. You can use

全局安装create-react-app

npm install create-react-app -g

//用它创建项目

create-react-app react-demo

//启动项目

npm run start

然后安装antd

npm install antd --save

按需引入Ant-Design插件
需要两个插件：
1、react-app-rewired（一个对 create-react-app 进行自定义配置的社区解决方案）。
git地址：https://github.com/timarney/react-app-rewired/

npm install react-app-rewired -D

/* package.json */
"scripts": {
-   "start": "react-scripts start",
+   "start": "react-app-rewired start",
-   "build": "react-scripts build",
+   "build": "react-app-rewired build",
-   "test": "react-scripts test --env=jsdom",
+   "test": "react-app-rewired test --env=jsdom",
}

然后在项目根目录创建一个 config-overrides.js 用于修改默认配置。

module.exports = function override(config, env) {
  // do stuff with the webpack config...
  return config;
};

2、babel-plugin-import （一个用于按需加载组件代码和样式的 babel 插件）。

npm install babel-plugin-import -D

修改 config-overrides.js 文件。

const { injectBabelPlugin } = require('react-app-rewired');

  module.exports = function override(config, env) {
   config = injectBabelPlugin(['import', { libraryName: 'antd', libraryDirectory: 'es', style: 'css' }], config);
    return config;
  };

经过上面两部的操作，我们的antd的按需引入就设置好了。在组件中直接这么用

随后我就启动项目：

$ npm run start

> [email protected] start E:\aPritice\appnfc
> react-app-rewired start

The "injectBabelPlugin" helper has been deprecated as of v2.0. You can use customize-cra plugins in replacement - https://github.com/arackaf/customize-cra#available-plugins

就直接报错了，跟着报错，进到这里https://github.com/arackaf/customize-cra#available-plugins
，就看到一句话：Override webpack configurations for create-react-app 2.0，react-scripts 升级到 2.1.2 以后破坏了 react-app-rewired，react-app-rewired的新版本删除所有方法injectBabelPlugin，这些方法被移动到一个名为’customize-cra’的新包中了

所以现在你可以开始下载这个包还有less,less-loader了
npm 方法：

npm install customize-cra --save-dev
npm i less
npm i -D less-loader

yarn方法：

yarn add customize-cra --dev
yarn add less
yarn add --dev less-loader

下载完，修改下
config-overrides.js

const {
    override,
    fixBabelImports,
    // addLessLoader,
} = require("customize-cra");


module.exports = override(
    fixBabelImports("import", {
        libraryName: "antd", libraryDirectory: "es", style: 'css' // change importing css to less
    }),
    // addLessLoader({
    //   javascriptEnabled: true,
    //   modifyVars: { "@primary-color": "#1DA57A" }
    // })

);

然后就可以重新

npm run start

然后页面就可以正常运行了
