运行后：

rails generate active_admin:resource Project

在终端我收到以下错误：

/Users/thalatta/.rbenv/versions/1.9.3-p448/lib/ruby/gems/1.9.1/gems/activesupport-4.0.0/lib/active_support/dependencies.rb:460:in `load_missing_constant': Circular dependency detected while autoloading constant User (RuntimeError)
from /Users/thalatta/.rbenv/versions/1.9.3-p448/lib/ruby/gems/1.9.1/gems/activesupport-4.0.0/lib/active_support/dependencies.rb:183:in `const_missing'
from /Users/thalatta/code/byrdtyme/app/admin/user.rb:1:in `<top (required)>'

这是我的 Gemfile 供参考：

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.0'

# Use sqlite3 as the database for Active Record

group :doc do

end

我尝试遵循这篇文章的建议：自动加载常量 User 时检测到循环依赖，但不幸的是，据我所知，activesupport 没有可以发布问题或查看问题是否已解决的 github。

谢谢你的时间！

尝试删除第二次提及 gem 'rspec-rails'

另外 - 检查您的用户控制器的第一行......它应该是：

类用户控制器 < 应用控制器

之前有人遇到过这个错误，因为他们有 'UsersControllers' 而不是 UserController（参见这篇文章：Rails 4 Runtime error in controller: Circular dependency detected while autoloading constant）。

您的新 Gemfile 将如下所示：

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.0'

# Use sqlite3 as the database for Active Record
gem 'sqlite3'

# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.0'

gem 'ransack'
gem 'activeadmin',         github: 'gregbell/active_admin', branch: 'rails4'
gem 'formtastic',          github: 'justinfrench/formtastic'
