rails g active_admin：安装错误

Question

我在使用ActiveAdmin时遇到问题。 我已将gem'activeadmin'添加到我的Gemfile中并运行

$ bundle install

起作用了。 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>'

也许这真的很愚蠢，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 。 重命名它，一切都会正常。

要重命名应用程序，请查看此线程以获取说明。

Answer 2

总体来说，这听起来好像您正在正确地做事。

我添加了宝石“ active_admin”

从文档中可以看到：

# Gemfile

gem 'activeadmin' 

有帮助吗？
