node.js - Uncaught SyntaxError: Unexpected token < while deploying to Heroku

问题描述

我在 Heroku 上部署了一个 MEAN 应用程序。但是不断收到这个 Uncaught SyntaxError: Unexpected token <. 在控制台中，它说它位于公共文件夹中的 index.js 文件中。它来自 Traversy Media 的 MEAN APP 教程系列。我在 package.json 文件中添加了“start”：“node app.js”和节点引擎版本。在我的 .gitignore 中，我只有 node_modules/ 。我似乎真的找不到这里的问题。

这是heroku构建日志
