https://unpkg.com/@antv/layout@latest/dist/layout.min.js. G6源码中有用到这个cdn，这个cdn现在资源被移除了，导致线上项目崩溃 #5642

<!-- Answer -->

It appears the CDN link for the @antv/layout package used in your G6 project is no longer accessible, causing your online project to crash. Here are steps to resolve the issue:

1. Check for an Updated CDN Link: Visit the AntV official website or their GitHub repository for a new CDN link for the @antv/layout package.

2. Download and Host the Package Locally: To avoid future CDN issues, download the @antv/layout package (via npm install @antv/layout) and serve the layout.min.js file from your server.

3. Use a Package Manager: Add @antv/layout to your project dependencies using npm or Yarn (npm install @antv/layout or yarn add @antv/layout). This ensures the package is included in your project's build output.

4. Update Your Import Statements: Reflect the new location of the @antv/layout package in your codebase. For example, after installing the package, you can import it directly in your JavaScript or TypeScript files:

import { DagreLayout } from '@antv/layout';

5. Fallback to an Alternative CDN: As a temporary fix, search for alternative CDNs like jsDelivr or cdnjs that might host the @antv/layout package.

These steps should help you mitigate the issue with the missing CDN resource and prevent similar problems in the future.

看起来是 unpkg 服务器的问题，尝试使用:

• jsdelivr : https://cdn.jsdelivr.net/npm/@antv/layout@latest/dist/layout.min.js
• npmmirror: https://registry.npmmirror.com/@antv/layout/latest/files/dist/layout.min.js

看起来是 unpkg 服务器的问题，尝试使用:

• jsdelivr : https://cdn.jsdelivr.net/npm/@antv/layout@latest/dist/layout.min.js
• npmmirror: https://registry.npmmirror.com/@antv/layout/latest/files/dist/layout.min.js

并不是unpkg服务问题，而是@antv/layout这个包，在0.x的版本是存在layout.min.js文件的，但是latest版本1.x目前文件被移除了。 所以可以配置layout的workerScriptURL属性为：

• https://unpkg.com/@antv/layout@0.x/dist/layout.min.js
• jsdelivr : https://cdn.jsdelivr.net/npm/@antv/layout@0.x/dist/layout.min.js
• npmmirror: https://registry.npmmirror.com/@antv/layout/0.x/files/dist/layout.min.js

也可以改成使用本地worker：

new G6.Graph({
  ...,
  layout: {
    ...
    workerScriptURL: new URL('@antv/layout/dist/layout.min.js', import.meta.url).toString(),
  }
});
