在我部署了我的 Angular 7 应用程序并尝试在浏览器上打开它后，我收到错误 500。检查日志我发现：

A  FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory 
A   1: node::Abort() [node]

问题是，如果你用谷歌搜索FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory，修复应该将 package.json 起始行更改为 this "start": "node --max_old_space_size=4096 dist/server",。这样，日志中的错误就消失了，但页面仍然给出错误 500，现在日志仅显示以下内容：

F  GET 500 0 B 3.3 s Chrome 70 / GET 500 0 B 3.3 s Chrome 70 5cb9a64b00ff0dd3429e5e7b0e0001657e6e6f6c696665000166726f6e74656e643a323031393034313974313333353337000100
A  Node Express server listening on http://localhost:8080

也许我需要在 app.yaml 文件中写入更多内容或更改它，现在它看起来像这样：

runtime: nodejs8
env: standard
service: frontend

我的 Angular 应用程序也是服务器端渲染的，不使用 firebase。

我让它工作了。问题似乎在 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的 F1 并且那个类的内存太低了。现在我的 app.yaml 文件如下所示：

runtime: nodejs8
env: standard
service: frontend
instance_class: F2
