Question

我的这个应用程序在localhost的本地计算机上运行良好。但是无法部署在Google App Engine中。我已经使用app.yaml文件尝试了许多试验，但是无法成功部署它。 很可能是我错误地配置了app.yaml文件和package.json文件。

这是 full source code of the project

这是项目根目录（对于服务器）中package.json文件的关键部分。

    "scripts": {
        "server": "nodemon index.js",
        "client": "npm start --prefix client",
        "dev": "concurrently \"npm run server\" \"npm run client\"",
        "start": "cd client && npm install && npm run build && cd .. && npm run dev",
        "heroku-postbuild": "cd client && npm install && npm run build",
        "fix-code": "prettier-eslint --write 'src/**/*.{js,jsx}' ",
        "fix-styles": "prettier-stylelint --write 'src/**/*.{css,scss}' "
    },

在我的客户端目录（为我的React客户端提供服务）中，我有package.json for React

下面是我在项目根目录下的app.yaml code。

runtime: nodejs
env: flex

handlers:
  - url: /api/.*
    script: auto
  - url: /
    static_files: client/build/index.html
    upload: client/build/index.html
  - url: /
    static_dir: client/build

当我最终运行gcloud app deploy时，我得到了错误提示

**ERROR: (gcloud.app.deploy) Error Response: [9] 
Application startup error:

要从gcloud获取日志，我运行gcloud app logs tail -s default，它显示以下内容

Google AppEngine上的节点JS应用以npm run start开头。您需要使“启动”过程保持简单（请参见文档）。您正在“开始”脚本中更改文件夹，但是在AppEngine上没有这些文件夹。只要确保您的“开始”脚本很简单即可。

React + Node / Express + Mongo App-无法部署在Google App Engine中
