因为我是 Rails 新手，所以我尝试搜索解决方案并尝试关注
How to fix a slow implicit query on pg_attribute table in Rails
Error deplying to heroku #1825
如何解决此类错误的任何提示。
【问题讨论】：
【参考方案1】：花了 5 个小时后，我发现我没有运行迁移 所以如果你遇到同样的问题，这里是给其他人的
将[app_name] 替换为您在heroku 上的应用程序名称
heroku rake db:migrate --app [app_name]
【讨论】：
【参考方案2】：生活小窍门：在 heroku CLI 上执行 heroku run rails console 会给你一个更详细的错误细分，而不是逐行查看日志。
【讨论】：
以上是关于在heroku上成功部署后Rails应用程序无法正常工作？的主要内容，如果未能解决你的问题，请参考以下文章
