我正在学习Heroku文档（https://devcenter.heroku.com/articles/getting-started-with-nodejs）中的教程，并在运行命令时遇到了问题：

% heroku local web

在Mac（M1）上，虽然教程的第一部分都很顺利，但在 * 本地运行应用程序 * 一节中，我得到了以下结果（而不是应该发生的结果）：

在网上搜索似乎表明Mac可能会自己使用5000端口。当我在网页浏览器中查看http：//localhost：5000/时，5000端口似乎确实有点忙碌（尽管页面显示完全是白色）。但我不知道它在做什么。即使我重新启动计算机，情况也不会改变。
我一定不是唯一一个碰到这个问题的人。那么，处理这种情况并能够继续本教程结尾的正确方法是什么呢？
