Question

我刚从rails应用程序中删除了active_admin，现在又尝试再次添加active_admin。

getmfile：gem＆＃39; activeadmin＆＃39;，github：＆＃39; activeadmin＆＃39;

我运行了这个命令：

rails g active_admin:install

我遇到了这个错误：

Running via Spring preloader in process 4200
Expected boolean default value for '--markerb'; got :erb (string)
Could not find generator 'active_admin:install'. Maybe you meant 'devise:install', 'responders:install' or 'active_record:model'

更新：我运行了bundle install但没有反应

更新： rails -T

的结果

该问题与here

中所述的弹簧预紧器有关

重新启动spring preloader，您应该可以运行activeadmin generator命令。

命令停止弹簧

$ ./bin/spring stop

找不到生成器＆＃39; active_admin：install＆＃39;
