1、package.json添加如下，安装依赖：
"libpag": "^4.2.84",
"copy-webpack-plugin": "9.1.0", 为什么是写死的旧版本，后面解释
2、使用的方法，这里只是一个小示例，具体如何使用看个人（这里主要是想记录过程中出现的问题及解决方式）：
const init = async () => {
const PagInfo = await LibpagUtils.init() as any; // LibpagUtils为封装好的方法
playPag(PagInfo)
}
const playPag = (PagInfo: any) => {
const { url, repeatCount } = props || {}
const { PAGFile, PAGView } = PagInfo
fetch(url).then((response) => {
(window as any).globalThis = window;
return response.arrayBuffer()
}).then(async (buffer) => {
const pagFile = await PAGFile.load(buffer);
const pagView = await PAGView.init(pagFile, canvasRef.current);
// 判定监听事件
pagViewAddListener(pagView);
setPagView(pagView);
// 0 表示无限次
pagView.setRepeatCount(repeatCount || 0);
await pagView.play();
});
}
3、copy-webpack-plugin的使用，我这里是umi项目，在config/config.ts目录中添加如下：
const CopyPlugin = require('copy-webpack-plugin');
const path = require('path'); // 这个插件没有的话先安装
chainWebpack: (memo: WebpackChain) => {
...... // 其他的插件使用
memo.plugin('CopyPlugin').use(
new CopyPlugin({
patterns: [{ from: path.resolve(__dirname, '../node_modules/libpag/lib/libpag.wasm'), to: '../dist' }], // dist为打包后的静态文件路径
})
)
}
4、到这里都是很顺利的，本地调试播放也很顺利，但当在jenkins部署到测试时出现如下错误：

5、尝试了很多方式，都没找到出现问题的原因，最后找到了解决的方式，将copy-webpack-plugin从版本12多降到9.1.0解决问题。
