rails g active_admin:install 错误

Question

我对 ActiveAdmin 有疑问。我已经将 gem 'activeadmin' 添加到我的 Gemfile 和运行

$ bundle install

有效。但是当我尝试：

$ rails g active_admin:install

我得到：

/home/dominika/active_admin/config/application.rb:10:in `<module:ActiveAdmin>': superclass mismatch for class Application (TypeError)
from /home/dominika/active_admin/config/application.rb:9:in `<top (required)>'

from -e:1:in `<main>'

也许真的很蠢，但我真的不知道如何解决。请帮忙...

Answer 1

发生这种情况是因为您的应用程序名为 active_admin。重命名，一切正常。

重命名应用视图this thread获取说明。

Answer 2

总的来说，听起来你做事很正确。

I've added the gem 'active_admin'

从文档中可以看出：

# Gemfile

gem 'activeadmin'

有帮助吗？
