ruby-on-rails - 我的应用程序在 Heroku 上关闭，运行 "heroku run rails test"时没有错误，但运行 "heroku run rails console"时出现许多错误

Question

我的 rails 应用程序在推送到 heroku 时挂了

这是 heroku 应用程序日志的输出

我尝试运行 heroku restart，然后 heroku run rails console .. 我遇到了这些错误，

对不起，我还是新手，这只是我尝试使用“rails 教程”一书构建的注册系统。知道该应用程序在我的本地主机上运行良好，

据我所见，CarrierWave 存在错误。你想在你的一个程序文件中调用它，但它不在你的 gem 文件中。

如果您从现有项目中导入了一些 Ur 代码，请检查所有配置文件。
