我的应用程序在我的本地主机和 Heroku 上运行良好，直到我尝试通过他们的网站而不是 CLI 更改我在 Heroku 上的项目名称。现在，该应用程序仍然可以在我的本地主机上运行，但我收到应用程序错误和消息，应用程序中发生错误，无法提供您的页面。请稍后重试。如果您是应用程序所有者，请检查日志以了解详细信息。
此外，我正在运行Ruby Rails 3.2，并在项目中间更新到4.0，以尽可能保持最新状态，但它使整个过程变得更加复杂。
我刚刚开始编码，这个项目几乎完成了 - 只需要让它与主机和我的自定义域同步，这一切都变成了废话：/任何帮助将不胜感激。
这是我运行 Heroku 日志时得到的 --tail：

在 Heroku 中更改名称没有任何作用——但您必须在本地 git 存储库中使用以下行更改它：
git remote rm heroku
heroku git:remote -a newname
，你的应用程序中似乎有一些大错误。正如@KepaniHaole所说，您似乎有"薄"错误 - 您的GemFile中有宝石吗？
