推荐答案

你必须通知 heroku 从哪里开始:missing script: start.在你的 package.json 中，你应该有类似 this:

You have to inform heroku where to start : missing script: start. In your package.json, you should have something like this:

"scripts": {
  "start": "node index.js"
}

其中 index.js 是您的入口点.

Where index.js is your entry point.

作为替代，您可以在Procfile:

web: node index.js
