在我部署了我的角度7应用程序并尝试在浏览器上打开它之后，我得到错误500.检查日志我发现这个：

事情是，如果你谷歌FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory修复应该改变package.json开始行到这个"start": "node --max_old_space_size=4096 dist/server",。有了这个，日志中的错误消失了，但页面仍然给出错误500，现在日志只显示：

也许我需要在app.yaml文件中写更多内容或更改它，现在它看起来像这样：
runtime: nodejs8
env: standard
service: frontend
我的角度应用程序也是服务器端渲染，不使用firebase。
我搞定了。问题似乎出现在app.yaml文件中。我不得不将instance_class设置为F2。如果你没有设置你是默认F1并且那个类中的内存太低了。现在我的app.yaml文件如下所示：
runtime: nodejs8
env: standard
service: frontend
instance_class: F2
