我的test_app可以正常运行本地数据库
我还没有Heroku的工作经验。我刚刚推出了文件。
您是否已经解决了您的问题？
大卫提到：你需要为Heroku部署指定这些宝石。
确保您的 Gemfile和Gemfile.lock不包含在您的.gitignore文件中
你也可以在Heroku上使用Cedar堆栈。确保你使用了：
heroku create --stack cedar
heroku create
为Rails3应用程序。如果是Rails3.1，则需要进一步阅读：
http://devcenter.heroku.com/ articles / rails31_heroku_cedar
尝试 http：// ruby .railstutorial.org / 这本书是Heroku部署的免费漫游。
您也可以联系Heroku的支持。
如果您有进一步的问题，请在这里插入您的错误，Gemfile，Gemfile.lock （或者插入Guhub的Gist ）并分享它。

刚刚注意到：您可能不使用RVM，您也可能在使用Rake和其他gem版本时遇到问题。请参阅RVM： https://rvm.io
I trying to do a full verification install of Rails 3.1 pre and deploy to heroku.

My test_app runs fine with local db
I have no working experience with Heroku yet. I have just pushed files out there.
Have you solved your problem?
This might be what David mentioned: you need to specify these gems for Heroku deployment. Make sure your Gemfile and Gemfile.lock is not included to your .gitignore file.
Also you may wanna use Cedar stack on Heroku for. Make sure you used:
heroku create --stack cedar
instaed of
heroku create
for a Rails3 app. If it's Rails3.1 then it needs further readings:
http://devcenter.heroku.com/articles/rails31_heroku_cedar
Try http://ruby.railstutorial.org/ this book for free walkthrough on Heroku deployment.
You can contact to Heroku's support too.
If you've further question on it please insert your error, Gemfile, Gemfile.lock here (or into Guhub's Gist) and share it.

Just noticed: you probably don't use RVM and you may have problems with Rake and other gem versions too. Please see RVM: https://rvm.io
