将react应用上传到heroku以安装devDependencies

Question

我使用create-react-app创建react应用，并将该应用上传到heroku。当我尝试显示网站时，我看到了错误

我的package.json

  }
}

在创建react项目时，我也尝试使用默认脚本

     "scripts": {
    "start": "node scripts/start.js",
    "build": "node scripts/build.js",
    "test": "node scripts/test.js",

  },

但是我遇到同样的问题。 我阅读了一些关于stackoverflow的文章，但没有针对我的问题的有效解决方案。 我认为，当它在heroku服务器上运行时，它不会安装devDependencies，而只会安装依赖项。
