在react脚手架中，使用npm add antd安装最新的依赖以后，再使用import 'antd/dist/antd.css'全局引入会报错，报错原因显示为：
Module not found: Error: Can't resolve 'antd/dist/antd.css' in 'C:\Users\26396\Desktop\react-project\src'
这时进入下载的antd依赖文件中查看会发现找不到antd.css的文件，原因是使用默认add antd下载的是最新版本的依赖文件，如果要使用上方口令引入css样式文件，需要安装前一个版本的依赖，首先把原本的依赖卸载，使用的口令是：
npm remove antd
然后安装上一个版本的依赖，口令为：
npm add antd@^4.24.2
之后就可以正常引入css样式的文件，并且可以正常使用。
在引入时，引入如下：
import { Button } from 'antd';
import 'antd/dist/antd.css'
在终端npm start后控制台报错：

解决方法：
因为引入的import 'antd/dist/antd.css'不对，应该引入import 'antd/dist/antd.min.css'，注意全局查找引入antd样式的地方，进行全局修改，修改之后，报错消失，npm start正常运行。
