Question

我刚刚尝试了本地主机中的meanjs 0.4.0并运行良好，但是当我部署到heroku link to app并尝试＆＃34;注册＆＃34;选项我在navegator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heroku日志时，我得到：

我现在不知道该怎么做，因为Heroku支持告诉我错误是在我的代码中，但我还没有改变任何东西！

刚出现这个问题。我们能够通过在package.json＆gt;中强制执行我们的首选节点版本来解决它。发动机。

我们之前有过

JTextField

我们将其更改为

"node": ">=0.10.0"

然后将其推送到Heroku，这就解决了这个问题。

不完全确定问题是什么，但我们发现此链接导致我们相信节点版本是问题：

在部署到Heroku
