推到Heroku错误：contextify@0.1.14安装
我是一个新的node.js开发人员。 我试图推我的node.js应用程序到Heroku，但我不断收到一些错误如下，但不知道如何去解决它。

请帮帮我。 谢谢。
我已经解决了这个问题。 Contextify在节点4.x中不受支持。 所以我把节点降级到了0.10.x，然后工作正常。
对不起我的噪音。
我的第一个想法是查看package.json文件并检查错误。 同时检查包含在package.json 的每个npm包的版本，并确保它们是最新版本。
还要在package.json 定义最新版本的节点 。
Javascript /节点库可以定期更新，如果你正在按照教程，你可能需要更新一些软件包版本
