Ruby Heroku--站点不工作

我有一个在本地完全正常工作的站点，当我使用git push heroku master时，它似乎工作正常，但当我在浏览器中实际打开heroku站点时，我只收到一条消息：“很抱歉，出现了一些问题。我们已收到有关此问题的通知，我们将很快进行查看。”我不知道为什么会这样。有人能提出可能发生这种情况的原因吗？我应该从哪里开始调试这个问题？（或者如果你一下子就知道如何解决它，那就更好了）

这是我的heroku日志文件：

这意味着什么？这就是问题的原因吗？

您是否迁移了Heroku端的数据库

heroku-rake-db:migrate

---

可以在这里找到。

该消息是来自Heroku还是来自您的应用程序？使用命令行上的

Heroku日志

，查看错误。因此，我输入了

Heroku日志

，但我真的不懂其中任何内容，而且内容非常庞大--我不知道要查找什么。和@s.m.，当我访问应用程序的实际URL（app_name.heroku.com）时出现了错误@Kvass：我对heroku一无所知，但你可以将日志发布到pastebin之类的地方，编辑你的问题并添加一个链接，这样可能有人可以帮助你。日志是连续的，请向下查找错误（可能是堆栈跟踪），然后从那里向上滚动以查找错误的来源。此外，您还可以使用

$heroku logs>logfile.txt

将输出复制到文本文件中。我尝试了这个方法，但遇到了一个新问题。我使用'faker'gem进行测试（在开发环境中），并在我的一个rake文件（lib/tasks目录中）中有一行

require'faker'

。Heroku对此行有问题，说它找不到要加载的伪造文件--我如何解决此问题？显然，它找不到伪造的宝石，因为它只在我的gemfile中的开发组中。那么我该怎么办呢？解决这个问题后，我应该能够运行该命令，然后看看它是否解决了我最初的问题。@Kvass除非您有理由不这样做，否则您可以将它移到

Gemfile

的生产部分。应该不会有任何负面影响，我们就快到了。我只是这样做了，然后做了heroku rake db:migrate，站点也加载了，但是当我尝试使用注册并创建新用户时，出现了相同的原始错误消息。注册功能在我的本地主机上正常工作。实际上我收回了这一点——用户已正确登录，只是用户的显示操作没有正常工作。其余页面正在加载
