Heroku 上的节点应用程序失败

Question

我已经设法将https://github.com/hexojs/hexo 推送到heroku，但是当我在http://warm-shelf-26895.herokuapp.com/ 查看应用程序时，它完全失败了。

我是新手，谁能告诉我出了什么问题以及如何解决这个问题？太棒了

Answer 1

您应该在 package.json 中包含一个脚本部分，指定用于启动应用程序的正确节点命令。例如：

scripts": {
  "test": "echo \"Error: no test specified\" && exit 1",
  "start": "node app.js"
},
