npm ERR cb()从未调用

我有一个Node.js应用托管在Heroku。每次我做一个git push heroku，我得到以下错误:

错误在最后几行:

我以前把我的代码推送给Heroku没有任何问题;从星期一开始，我才出现这个错误。

我在网上看到过类似的帖子，提到的错误略有不同，但还没有看到一个![远程拒绝]master -> master(预接收钩子拒绝)之前。

重要!下面的解决方案现在被认为是不稳定的，你应该使用节点版本管理:Github上的节点版本管理器。David Walsh对NVM也有很好的介绍。NVM工作得非常出色，我已经用它管理遗留WordPress项目好几年了。

请不要使用这个——使用NVM

当我试图为WordPress安装Sage主题时，我就遇到了这个问题。当我在主题目录上运行npm install时，它失败了。

在包中查找依赖项。json时，我可以看到我为Node运行的引擎已经过时。在命令行上运行node -v显示我的版本是v0.10.9，而Sage的最新版本要求>= 0.12.0

这就是解决方法。这些步骤来自David Walsh的博客

清除npm缓存:sudo npm cache clean -f 安装最新版本的Node helper: sudo npm Install -g 告诉helper (n)安装Node: sudo n stable的最新稳定版本

然后你会看到一个进度显示，在此之后你会得到最新的信息。

当我运行npm install之后，一切工作正常，我能够运行gulp来构建初始dist目录。
