Heroku App根據日誌不斷崩潰...爲什麼？

Question

當我部署的應用程序，並從本教程炒高代碼： http://blog.superpat.com/2011/06/14/node-js-chat-demo-on-heroku/

我從Heroku的收到此錯誤： 「在應用程序中出現錯誤，你的頁面無法送達，請再試一次在幾分鐘的時間。

如果您是應用所有者，請檢查您的日誌的詳細信息「。

這裏是我得到的日誌錯誤：

我跟着從教程github上的所有代碼。

什麼可能導致它？它與pg有什麼關係？我是否應該在某處更改數據庫路徑？

當我嘗試在本地使用節點server.js運行它，但我得到這個錯誤：

Error: Cannot find module '/home/euridice/node_modules/pg/lib/native/../../build/default/binding' 
at Function.Module._resolveFilename (module.js:338:15) 
at Function.Module._load (module.js:280:25)

at Module.load (module.js:356:32) 
at Function.Module._load (module.js:312:12) 
at Module.require (module.js:364:17) 

這是什麼意思？

編輯：修正了一些東西，現在我越來越：

events.js:72 
    throw er; // Unhandled 'error' event 
     ^
Error: FATAL: password authentication failed for user "postgres" 
FATAL: password authentication failed for user "postgres" 

at Connection.<anonymous> (/home/euridice/node_chat/node_modules/pg/lib/native/index.js:187:17)

Answer 1

運行

npm install 

本地，也推 「node_modules」 文件夾中的Heroku

編輯：我想你誤解了一些git和herkoku的概念。您需要：

1. clone the repository: 'git clone git://github.com/metadaddy-sfdc/node_chat.git' 
2. go into the repository: 'cd node_chat' 
3. now you can run 'npm install' in THAT folder 
4. after that you can create your heroku app: 'heroku create' 
5. and deploy that to heroku: 
    5.1 git add . 
    5.2 git commit -m "some comment" 
    5.3 git push heroku master 

必須將）在你的node_chat文件夾，B）第一NPM安裝，然後推EVERYTHING（GIT添加）到Heroku的！
