尝试将Node.js项目部署到Google App Engine时出错

Question

I am trying to deploy my node.js project to my App Engine project. the command I use is gcloud preview app deploy app.yaml .

This is my app.yaml file:

runtime: nodejs
vm: true
skip_files:
  - ^(.*/)?.*/node_modules/.*$

and this is the error I get: ERROR: (gcloud.preview.app.deploy) We were unable to detect the runtime to use for this application. Please specify the [runtime] field in your application yaml file or check that your application is configured correctly. ERROR: (gcloud.preview.app.deploy) We were unable to detect the runtime to use for this application. Please specify the [runtime] field in your application yaml file or check that your application is configured correctly.

I'm pretty sure I have set up the project correctly, and have also gcloud init my gcloud CLI.

Any help'd be appreciated!

EDIT:

Try adding --verbosity=debug to your "gcloud preview app deploy" command to see what's going on. Most likely, there's something else about your application that gcloud doesn't recognize, like a missing or invalid package.json. This is being badly reported as an unrecognized runtime.

To be recognized as a node.js app, you must either have a server.js file or have a package.json file with a "scripts" section specifying a "start" command.
