我有一个项目，我可以在本地运行，似乎没有任何问题推向Heroku，但随后崩溃。
这是我在进行git推送时所看到的。

http://glowing-mist-2689.herokuapp.com deployed to Heroku
这是我在进行heroku日志时看到的内容。
2012-04-22T01:04:05+00:00 heroku[slugc]: Slug compilation finished
2012-04-22T01:04:08+00:00 heroku[web.1]: Starting process with command `node run.js `
2012-04-22T01:04:08+00:00 app[web.1]: Error: No such file or directory - node run.js

2012-04-22T01:04:10+00:00 heroku[web.1]: State changed from starting to crashed
在Procfile中web: node run.js
可能是什么问题？有没有办法可以检查远程目录中是否存在run.js？
