@shengcp I can't help you debug webpack configuration, you can use kkt or create-react-app

I suspect it is your Babel configuration problem. You can check it.

https://babeljs.io/docs/en/babel-plugin-syntax-dynamic-import

npm install --save-dev @babel/plugin-syntax-dynamic-import
{
  "plugins": ["@babel/plugin-syntax-dynamic-import"]
}
