Module parse failed: Unexpected character '@' (1:0)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
> @import '../../style/default';
| // @import '../../style/mixins/index';
```

Reproduce the import of @ant-design/compatible's Comment component and inspect the reported node_modules/@ant-design/compatible/es/comment/style/index.less path. Start by checking how this package is processed by the project's existing bundler configuration. Done means the import builds without the reported Unexpected character error.
