我正在关注Ruby on Rails Web开发的Michael Hartls教程，并在第7章结束时报告了注册（http://ruby.railstutorial.org/chapters/sign-up#sec-tests_for_user_signup）。
在我的localhost上启动应用程序工作正常，并将其启动到Heroku，直到本章，但现在我得到了H10错误。
我查看了heroku日志，但似乎没有任何语法或未安装的gemfiles。我还在heroku上打开网站之前运行了heroku run rake db：migrate。但是我仍然得到同样的错误。
如果可以的话，非常感谢任何帮助。 谢谢你的时间。

答案 0 :(得分：3)
阅读你的日志（这是一门艺术品来阅读' - 你会改进），从上面可以看出你有这个错误：
/app/config/environments/production.rb:33: syntax error, unexpected keyword_in, expecting keyword_end (SyntaxError)
查看你的app/config/environments/production.rb - 我打赌你会在那里找到你的错误。
它可能永远不会在本地出现，因为你没有在生产模式下运行。
