为您的项目创建一个版本npm run build,然后像这样创建app.yaml文件

env: standard    
runtime: nodejs10    
service: default    
handlers:
  - url: /static
    static_dir: build/static

  - url: /assets
    static_dir: build/assets

  - url: /(.*\.(json|ico|js))$
    static_files: build/\1
    upload: build/.*\.(json|ico|js)$

  - url: .*
    static_files: build/index.html
    upload: build/index.html
您可以根据构建文件夹结构修改app.yaml
