长期以来，我一直在为看似简单的解决方案而苦苦挣扎。我是打字稿的新手，也是反应新手。
我正在尝试使用 react-muli-carousel NPM 包。
我能够让 customButtonGroup 在沙箱中成功工作： https ://codesandbox.io/s/fervent-rain-332mn?file=/src/App.js:834-913
但是当我尝试在我的 SPFX 解决方案中实现它时，我收到以下错误：
Type '{}' is missing the following properties from type '{ [x: string]: any; next: any; previous: any; goToSlide: any; }': next, previous, goToSlide
