Ruby on Rails Bundler activeadmin gem 安装错误

Question

我在尝试安装 activeadmin gem 时遇到了问题。我正在使用 Ruby 2.0 和 Rails 4.0.2。

这是我在项目目录中运行“捆绑安装”时得到的结果：

C:\Users\Samuel\Desktop\RubyonRailsWorkspace\GroupSRailsProjectNew>bundle install

a851e9f78b2ca'

这是我运行“gem install activeadmin”时得到的结果：

C:\Users\Samuel\Desktop\RubyonRailsWorkspace\GroupSRailsProjectNew>gem install activeadmin
ERROR:  While executing gem ... (Gem::DependencyError)
Unable to resolve dependencies: rails requires activesupport (= 3.2.16), actionpack 
(= 3.2.16); actionmailer requires actionpack (= 3.2.16); activeresource
requires activesupport (= 3.2.16); meta_search requires activesupport (~> 3.1),
actionpack (~> 3.1); activerecord requires activesupport (= 3.2.16); activemodel

sl (~> 1.3.2), rdoc (~> 3.4), activesupport (= 3.2.16), actionpack (= 3.2.16)

这是我的 GemFile：

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.2'

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

gem 'jbuilder', '~> 1.2'

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end

gem 'execjs'
# gem 'therubyracer'

# Use ActiveModel has_secure_password

# Use unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
# gem 'capistrano', group: :development

# Use debugger

如果能解决此问题，我们将不胜感激。

您正在从windowscmd 运行bundle install，而已经开始从cygwin shell 运行它，尝试从cygwin shell 运行它，因为我看到你已经混合了本机windows , 和 cygwin 路径样式向上。

Answer 2

您尝试安装的 gem 需要 rails 3.2.* 并且您使用的是 4.0。要么降级铁轨，要么使用另一颗宝石。

使用它为 rails 4 安装 activeadmin：Active admin install with Rails 4

gem 'activeadmin', github: 'gregbell/active_admin', branch: "rails4"
