我用active_admin界面编写了简单的统计应用程序，但我不想将其托管在heroku上。当我输入git push heroku master时，出现以下错误：

在我的Gemfile我有：gem 'activeadmin', github: 'gregbell/active_admin', branch: 'rails4“
我试图删除gemfile.lock并重新捆绑所有内容，但仍无法正常工作。有任何想法吗？
看来active_admin的rails4分支已删除！
您可以更新gemfile并指定标签或提交引用。截至目前，v0.6.1是最新版本，因此您可以执行以下操作：
gem "activeadmin", github: "gregbell/active_admin", tag: "v0.6.1"
..那将解决您的问题。另外，正如您在评论中指出的那样，选择另一个特定的修订版也可以消除该错误。
gem "activeadmin", github: "gregbell/active_admin", ref: "82ff48d51525bdf55c96e50d8650d45f2a6716ed"
