React 不支持 Antd 源映射

Question

我有一个关于在 CRA (create-react-app) 中集成 Ant Design 库的问题。

在我尝试按照他们的documentation 的要求集成它之后，如果没有集成 Craco，我总是会收到以下 4 个警告：

我使用以下版本：

"antd": "^4.19.2",
"react": "^17.0.2",
"react-dom": "^17.0.2",
"react-router-dom": "^5.1.2",
"react-scripts": "5.0.0",

有人可以帮我解决这个问题吗？谢谢！

Answer 1

react-script 升级到 5.0.0 后出现这个问题 解决方案：

- import 'antd/dist/antd.css

替换为：

+ import 'antd/dist/antd.min.css

Answer 2

不过，我只是通过集成 CRACO 和 LESS 成功地消除了错误。换上src/App.tsx：

- import '~antd/dist/antd.css';
+ import '~antd/dist/antd.less';

所以，据我所见，问题可能出在import '~antd/dist/antd.css'; 上，在src/App.tsx 中导入。

Answer 3

之前的解决方案对我不起作用，因为虽然它消除了编译错误，但它破坏了应用程序的所有 Antd 样式。

我们找到了这个解决方案：

导入'antd/dist/antd.min.css'

来自this Chinese site。

更个性化的解决方案是使用customize-cra

其实the issues of their repo!中也解决了

Answer 4

在花了很多时间解决这个问题之后， 我发现将GENERATE_SOURCEMAP=false 添加到您的 .env 文件将消除错误。

据说这是Webpack 5造成的。
