Ruby on rails Rails控制台在Digital Ocean上不与Dokku一起工作

我已经把我的Rails应用程序推到了一个Digital Ocean Dokku droplet上，除了Rails控制台之外，其他一切都正常工作。当我运行

dokku run myapp rails c

时，出现以下错误：

该应用程序安装在一个干净的水滴上。Dokku只安装了一个插件（Postgres）。

向Gemfile添加

gem'rb readline

解决了问题。

尝试使用

RAILS\u ENV\u name

@Avdept设置Environment感谢您的贡献！运行

dokku运行myapp rails c rails\u ENV=production

。仍然是相同的错误。请尝试使用

RAILS\u ENV=ENV\u name

@Avdept设置environment谢谢您的贡献！运行

dokku运行myapp rails c rails\u ENV=production

。还是一样的错误。
