javascript - 我无法在 Heroku 中运行我的 ReactJS 应用程序

Question

当我运行 npm start 时它可以工作，但在 heroku 中我不能这样做，

2017-06-28T17:18:54.167693+00:00 app[web.1]: npm ERR! code ELIFECYCLE

我的package.json，我在网上看到，也许这就是问题

<!-- language: lang-js -->

    {
      "name": "juego-cartas-reactjs",
      "version": "0.1.0",
      "main":"src/index.js",
      "dependencies": {
        "font-awesome": "^4.7.0",
        "lodash.shuffle": "^4.2.0",
        "react": "^15.6.1",
        "react-dom": "^15.6.1",
        "react-flipcard": "^0.2.1"
      },
      "devDependencies": {
        "react-scripts": "1.0.7"
      },

      "scripts": {
        "start": "react-scripts start",
        "build": "react-scripts build",
        "test": "react-scripts test --env=jsdom",
        "eject": "react-scripts eject"
      }
    }

我不知道还能做什么，如果有人知道这件事，帮忙

npm start 仅用于本地开发。你不应该在 Heroku 上使用它。

将 Create React App 项目部署到 Heroku follow Heroku's official guide to it 。

cd my-app
git init
heroku create -b https://github.com/mars/create-react-app-buildpack.git
git add .
git commit -m "react-create-app on Heroku"
git push heroku master
heroku open

本文链接自Deployment section of the User Guide随您创建的应用程序一起提供。我建议在那里寻找可能的答案。
