以下の通りにpackage.jsonとweb.jsを記述しherokuにデプロイしましたが、以下のエラーでデプロイできません。

package.json

```

      1 {
      2   "name": "app_name",
      3   "version": "0.0.1",
      4   "private": true,
      5   "devDependencies": {
      6     "http-server": "^0.8.0",
      7     "bower": "1.4.1",
      8     "express": "4.13.0"
      9   },
     10   "engine": {
     11     "node": "0.12.4",
     12     "npm": "2.10.1"
     13   },
     14   "scripts": {
     15     "postinstall": "bower install",
     16     "prestart": "npm install",
     17     "start": "http-server -a localhost -p 8000 -c-1"
     18   }
     19 }
    
```

web.js

```

      1 var express = require('express');
      2 var app = express();
      3 var port = Number(process.env.PORT || 8000);
      4
      5 app.use(express.static(__dirname + '/'));
      6 var server = app.listen(port, function(){console.log('Listening on port %d', server.address().port);});
    
```

エラーを見る限りbower install
ができていないみたいですが、どこが間違っているのかわからない状況です。どなたかおわかりになるかたぎ教授ください。よろしくおねがいします。

補足:  
ちなみにこのpackage.jsonはhttps://github.com/angular/angular-seedを参考にしました。

question
angularjs node.js heroku デプロイ
herokuにAngularJSのアプリをNodeを使ってデプロイしたい。
自己解決しました。  
devDependenciesは開発用の記述で本番庸ではdependenciesを書かなければなりませんでした。
