Question

我想将activeadmin用于我的rails项目，因此我将其添加到 gemfile 。

 gem 'activeadmin'

并更新了捆绑包，但收到了此错误消息 -

Resolving dependencies...
Bundler could not find compatible versions for gem "actionpack":
  In Gemfile:
    activeadmin (>= 0) ruby depends on
      actionpack (~> 3.0.0.rc2) ruby

    rails (= 4.0.0) ruby depends on
      actionpack (4.0.0)

我在github上传了这个项目;这是 gemfile - https://github.com/Mashpy/esl/blob/master/Gemfile

的链接

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'

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'

# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'

gem 'turbolinks'

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder

#gem
 gem 'activeadmin'

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

我做错了什么阻止我添加activeadmin？

Answer 1

Active Admin还有一些其他依赖项。看看Active Admin install with Rails 4。

将所有宝石（在最上面的答案中）复制并粘贴到您的gem文件中，运行bundle时不应该有任何问题。

Answer 2

您可以使用 -

更新套装

bundle update

然后

bundle install

确保宝石的配置正确。

Answer 3

我认为你应该升级这些宝石：

sass-rails ~> 3.2.3
coffee-rails ~> 3.2.1
