我正在使用dotlottie/react-player，webpack 4和react 16。在编译获得以下模块时，解析失败错误。

"@dotlottie/react-player": "^1.6.5" 
"webpack": "^4.44.2",
"react": "16.14.0",`

个字符
我在这里缺少哪个文件加载器？

I have tried using babel loader but then getting the below error
`ERROR in ./node_modules/@dotlottie/common/dist/chunk-BHJSY5WG.js 229:8
Module parse failed: Unexpected token (229:8)
File was processed with these loaders:
 * ./node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.
