我有一个带有物料用户界面的React / typescript项目。更新material-ui之后，我收到错误消息：
“一个接口只能扩展一个类或另一个接口。”
指向下面的导出行。首先，实际的错误是什么，这是有效的，但是对于另一个打字稿版本还是material-ui / typescript / react-package组合中存在严重的错误/不匹配？...第二，我该如何解决它？
...
type SystemProps = PropsFor<BoxStyleFunction>;
type ElementProps = Omit<React.HTMLAttributes<HTMLElement>, keyof SystemProps>;
export interface BoxProps extends ElementProps, SystemProps { //<-- error on this line
// styled API
component?: React.ElementType;
clone?: boolean;
// workaround for https://github.com/mui-org/material-ui/pull/15611
css?: SystemProps;
}
declare const Box: React.ComponentType<BoxProps>;
export default Box;
这是我的package.json：
