Question

我有一个node.js应用程序不是Web应用程序。这是我的package.json：

{
  "name": "myapp-backend",
  "version": "1.0.0",
  "description": "MyApp PubNub backend",
  "main": "app.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "repository": {
    "type": "git",
    "url": "https://git.heroku.com/myapp.git"
  },
  "keywords": [
    "backend"
  ],
  "author": "Pete Gu",
  "license": "ISC",
  "dependencies": {
    "pubnub": "^4.3.3"
  },
  "engines": {
    "node" : "6.9.2"
  }
}

Procfile的内容：

app: node app.js

我运行heroku local时会运行。但是，在推送代码并使用heroku logs检查日志后，我看到了这一点：

...这对我来说完全没有意义 - 为什么heroku尝试使用npm start而不是阅读Procfile启动应用？

Answer 1

Heroku似乎正在尝试启动web dyno，似乎并不知道你的Procfile。

您确定已将Procfile添加到git仓库吗？

无论如何，试试这个：

heroku ps:scale web=0
heroku ps:scale app=1

您还可以在package.json的“scripts”部分添加“start”：“node app.js”。

Answer 2

我可以看到错误缺少脚本：开始所以你需要添加

"scripts": {
"start": "node bin/xxx" //your main file name
}

将此添加到package.json。

Heroku node.js应用程序在本地运行但远程崩溃
