vue2项目从webpack3升级至webpack5线上环境报错，如何解决？
公司项目从webapck3升级到webpack5, 打包上线以后白屏，报这个错误，请问该如何解决，似乎只要引入如ECHART，axios之类的依赖，就会报出这个错误，不引入就是正常的，该如何对webpack进行配置，以下是报错截图和我的webpack配置，还请各位教教,框架地址https://github.com/1443290403/fronted_frame.git

你可以看看这个大佬的记录是不是可以解决你的问题
你把依赖排除啦
报错截图：
根据报错信息，是因为在webpack5中引入了新特性chunk loading using JSONP，导致了跨域问题。解决办法有两种：
- 在webpack配置中添加
crossOriginLoading选项，将其设置为"anonymous"，表示允许跨域加载资源：
module.exports = {
// ...
output: {
// ...
crossOriginLoading: 'anonymous'
}
// ...
}
- 在html文件中手动添加
crossorigin属性，也是为了解决跨域问题：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Webpack App</title>
<script src="dist/main.js" crossorigin="anonymous"></script>
</head>
<body>
<!-- ... -->
</body>
</html>
其中，crossorigin属性值为anonymous表示允许跨域加载资源。
