在Heroku上部署node.js

Question

我尝试将node.js测试应用程序部署到heroku，从heroku日志文件中收集的信息来看，它运行良好

但是当我运行url时，它不会显示应用程序，而只会显示自述文件而不是index.html文件。 我的应用程序在本地运行良好，并使用express.js和angular

谢谢

好的，所以我意识到我没有加载Bower组件，因此正在加载angular或jquery等。

我在这里找到了修复程序http://xseignard.github.io/2013/02/18/use-bower-with-heroku/

和这里https://devcenter.heroku.com/articles/node-best-practices

我在package.json文件和安装后添加了Bower作为依赖项

"scripts": {
  "postinstall": "bower install",
  "start": "node app.js"
},
"dependencies": {
  "bower": "1.8.0"
}
