React应用程序在本地运行，在Heroku错误代码= H10时崩溃

Question

在Windows中执行“ npm start”后，该应用程序运行良好，但是当我从github拉入Heroku时，我只会遇到一个错误。

package.json：

{
  "name": "tic-tac-toe",
  "version": "0.1.0",

  "dependencies": {
    "react": "^15.5.4",
    "react-dom": "^15.5.4"
  },
  "engines": {
      "node": "6.10.3",
      "npm":"3.10.10"
  },
  "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"
  }
}

和错误日志：

 app[web.1]: npm ERR!     npm bugs tic-tac-toe
 app[web.1]: npm ERR! Or if that isn't available, you can get their info via:
 app[web.1]: npm ERR!     npm owner ls tic-tac-toe
 app[web.1]: npm ERR! There is likely additional logging output above.

问题的性质使我认为这是基于配置的，而不是在主要的app.js代码中。主文件有点长，所以如果您想查看它，我会在Github上链接到它：https : //github.com/owenpercoco/React-Tac-

Heroku默认不安装devdependencies ：。https://devcenter.heroku.com/articles/nodejs-
support
。将您的react-
scripts模块设置为始终安装或关闭Heroku上的生产模式。
