Question

创建了一个新的rails 5应用程序，只有一个控制器用于静态页面，我正在尝试将其推送到Heroku开始。我不确定是什么导致heroku上的错误。无法找到任何具体信息。可能导致问题的原因是什么？

您可以尝试以下方法：

尝试重新启动应用程序，如果它可以正常运行...... [/ li>！
因为它是一个pg错误，请尝试运行rake命令*

rake db：create

rake db：setup

rake db：reset

rake db：migrate

*不要一次全部运行它们，运行一个并检查错误消息是否发生变化。

最后，评论pg gem和bundle并再次推送。

希望有所帮助......

我刚刚意识到，您是否已将 heroku postgres 插件添加到您的应用中？转到仪表板，如果没有，请添加。
