rollup打包时怎么排除第三方组件所引进的样式文件

[gogoinga]

项目中，import了一个第三方组件的css文件，打包后出现在了输出文件的styleInject里，请问我要怎么排除掉这个样式文件的打包呢
例如：
import 'node_modules/第三方组件/第三方.css';
import styles from './本地的.less';

(I ran your issue through Google translate, so hopefully I'm answering this correctly)

to exclude a file, I believe you need to set it as external, which is explained in this comment: rollup/rollup#497 (comment)

if that doesn't work for you, you may have better luck asking on the rollup repo! good luck!
