我对Java一无所知，但是我需要使用时间轴软件，并且喜欢在vis-timeline中看到的功能。我从git（https://github.com/visjs/vis-timeline）下载了它，然后按照git的说明安装了它并运行提供的测试时间表。
但是，我无法使其正常运行。运行“测试”示例时，出现以下错误：
> vis-timeline@5.1.0 test C:\Users\My User\Documents\vis-timeline
> mocha --exit --require @babel/register
C:\Users\My User\Documents\vis-timeline\node_modules\hammerjs\hammer.js:2643
})(window, document, 'Hammer');
^
ReferenceError: window is not defined
