前提：本文基于：基于Node.js 搭建React.js开发环境

第一步：React.js 项目集成UI框架（antd）

执行如下命令：cnpm add antd

C:\react_workspace\one>cnpm add antd

+ antd@4.9.4 
added 59 packages from 31 contributors in 123.276s

第二步：修改 src/App.js，引入 antd 的按钮组件

 
import React from 'react'; 
import { Button } from 'antd'; 
import './App.css'; 
 
const App = () => ( 
  <div className="App"> 
    <Button type="primary">Button</Button> 
  </div> 
); 
 
export default App; 

第三步：修改 src/App.css，在文件顶部引入 antd/dist/antd.css样式文件

@import '~antd/dist/antd.css'; 
.App { 
  text-align: center; 
} 
 
.App-logo { 
  height: 40vmin; 
  pointer-events: none; 
} 
 
@media (prefers-reduced-motion: no-preference) { 
  .App-logo { 
    animation: App-logo-spin infinite 20s linear; 
  } 
} 
 
.App-header { 
  background-color: #282c34; 
  min-height: 100vh; 
  display: flex; 
  flex-direction: column; 
  align-items: center; 
  justify-content: center; 
  font-size: calc(10px + 2vmin); 
  color: white; 
} 
 
.App-link { 
  color: #61dafb; 
} 
 
@keyframes App-logo-spin { 
  from { 
    transform: rotate(0deg); 
  } 
  to { 
    transform: rotate(360deg); 
  } 
} 

第四步：重新启动React.js 项目，访问http://localhost:3000
