【问题描述】：

我有一个几年前的项目（rails 4），我正在尝试更新（所有这些都是为了活动管理员的日期时间选择不起作用）——当我注释掉需要更新时把它全部更新好；但是如果我取消注释 squeel 以便它也更新，我会遇到这些依赖问题：

Bundler could not find compatible versions for gem "activerecord":

在 Gemfile 中： act-as-taggable-on 被解析为 4.0.0，这取决于活动记录 (>= 4.0)

annotate was resolved to 2.7.1, which depends on
  activerecord (< 6.0, >= 3.2)

friendly_id (~> 5.1.0) was resolved to 5.1.0, which depends on
  activerecord (>= 4.0.0)

pg_search was resolved to 1.0.6, which depends on
  activerecord (>= 3.1)

polyamorous was resolved to 1.3.1, which depends on
  activerecord (>= 3.0)

polyamorous was resolved to 1.3.1, which depends on
  activerecord (>= 3.0)

rails (~> 4.2.1) was resolved to 4.2.1, which depends on
  activerecord (= 4.2.1)

rails-erd was resolved to 1.4.7, which depends on
  activerecord (>= 3.2)

random_record was resolved to 0.0.8, which depends on
  activerecord (>= 3.0.0)

squeel was resolved to 0.5.0, which depends on
  activerecord (~> 3.1.0.alpha)

Bundler 找不到 gem "polyamorous" 的兼容版本：在 Gemfile 中：多角恋

ransack was resolved to 1.8.1, which depends on
  polyamorous (~> 1.3)

squeel was resolved to 0.8.10, which depends on
  polyamorous (~> 0.5.0)

Bundler 找不到 gem "sass" 的兼容版本：在 Gemfile 中： bootstrap-sass (~> 3.1.1) 被解析为 3.1.1.1，这取决于萨斯 (~> 3.2)

activeadmin was resolved to 1.0.0.pre4, which depends on
  bourbon was resolved to 4.0.0, which depends on
    sass (~> 3.3)

sass-rails (~> 4.0.1) was resolved to 4.0.5, which depends on
  sass (~> 3.2.2)

我尝试了几种不同的活动管理员组合，例如：

# gem 'activeadmin', '~> 1.0.0.pre2'
# gem 'activeadmin', github: 'activeadmin'
gem 'activeadmin', github: 'gregbell/active_admin'

或

# gem 'ransack',             github: 'ernie/ransack'
gem 'inherited_resources', github: 'josevalim/inherited_resources'
gem 'formtastic',          github: 'justinfrench/formtastic'
gem 'chosen-rails'
gem 'select2-rails'
gem 'active_admin_datetimepicker'
gem "active_admin-sortable_tree"
gem 'polyamorous', github: 'activerecord-hackery/polyamorous'
gem 'ransack', github: 'activerecord-hackery/ransack'

和

# gem "squeel"  # Last officially released gem
# gem 'squeel', github: 'activerecord-hackery/squeel'
# gem "squeel", :git => "git://github.com/ernie/squeel.git" # Track git repo

但似乎没有任何效果....

【问题讨论】：

您不会尝试升级到 Rails 5，是吗？
不，对我来说是 4.2

标签： ruby-on-rails ruby activerecord squeel

【解决方案1】：

虽然我仍在使用它（Rails 5 升级），但您可能想尝试将 activeresource 显式添加到您的 Gemfile 中。像这样：

gem 'activeresource', github: 'rails/activeresource'

gem 'activeadmin', github: 'activeadmin'
gem 'devise', '~> 3.4.1'

更新确实对我有用，至少到目前为止，并且没有使用其他依赖项，例如 ransack、draper 等，即使建议在他们的（ActiveAdmin 的）官方README 上使用。

试一试。
