GCloud VM 实例未启动节点应用程序

Question

我尝试运行在本地主机和 google VM 上安装我的节点应用程序。如果我登录到 Google 云虚拟机的 putty\ssh，应用程序运行没问题并启动节点应用程序（从 /opt/app 文件夹）。我可以登录浏览器并通过{外部 ip:port 号码}访问应用程序。

如果我只是重置（或stop\start）虚拟机，它不会启动应用程序。我提供了一个启动脚本来启动应用程序在以下文章中提到：

https://cloud.google.com/nodejs/getting-started/run-on-compute-engine#download_app

当 VM 尝试运行启动脚本文件时，我可以看到以下内容。这实际上是因为缺少依赖关系吗？因为如果 package.json 丢失，当我尝试手动运行时它应该会失败。

任何帮助将不胜感激？它还在 "supervisor" 日志中给出错误。

查看日志行 line 28: cd: /opt/app/7-gce: No such file or directory：在链接的说明中，它假定您的应用位于该目录中。但是，您的 VM 上似乎没有它，这会导致脚本的其余部分失败。
