当部署到 Heroku 时，meanjs 0.4.0 不工作

Question

我刚刚在本地主机上尝试了 meanjs 0.4.0 并且运行良好，但是当我部署到 heroku link to app 并尝试 "Sign up" 选项时，我在导航器控制台中得到了这个：

POST https://meanjsapptest.herokuapp.com/api/auth/signup 503 (Service Unavailable)

当我在 CLI 中编写命令和 heroku 日志时，我得到：

我不知道现在该怎么办，因为 Heroku 支持人员告诉我错误出在我的代码中，但我没有更改那里的任何内容！

刚遇到这个问题。我们能够通过在 package.json > engines.

中强制执行我们的首选节点版本来修复它

我们之前在

"node": ">=0.10.0"

我们改成了

"node": "6.6.0"

然后将其推送到 Heroku，问题就解决了。

不完全确定问题出在哪里，但我们发现这个 link 让我们相信节点版本是问题所在：
