Trouble upgrading Ruby on Rails from version 3.2.13 to 4.0.0

问题

For a my application I am trying to upgrade Ruby on Rails from version 3.2.13 to 4.0.0 and I am in trouble when installing / updating some gem (by using the Bundler), specifically the globalize3 gem. I am running Ruby 2.0.0-p247.

Given my Gemfile is:

gem 'rails', '4.0.0'

gem 'globalize3', github: 'svenfuchs/globalize3', branch: 'rails4'

gem 'delayed_job', :git => 'git://github.com/collectiveidea/delayed_job.git', :branch => 'master'
gem 'delayed_job_active_record', :git => 'git://github.com/collectiveidea/delayed_job_active_record.git', :branch => 'master'

# Added these gems to help with the transition to rails4:
gem 'protected_attributes'
gem 'rails-observers'
gem 'actionpack-page_caching'
gem 'actionpack-action_caching'
gem 'activerecord-deprecated_finders'

When I run the bundle install command in the Terminal window

Then I get the following output:

      activerecord (~> 3.0) ruby

    delayed_job_active_record (>= 0) ruby depends on

Bundler could not find compatible versions for gem "rails":
  In Gemfile:
    globalize3 (>= 0) ruby depends on
      rails (~> 3) ruby

    rails (4.0.0)

When I run the bundle update command in the Terminal window

Then I get the following output:

Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    globalize3 (>= 0) ruby depends on
      railties (~> 3.0) ruby

    coffee-rails (~> 4.0.0) ruby depends on
      railties (4.0.0)

Bundler could not find compatible versions for gem "actionpack":
  In Gemfile:
    rails (= 4.0.0) ruby depends on
      actionpack (= 4.0.0) ruby

    actionpack-action_caching (>= 0) ruby depends on
      actionpack (4.0.0.rc2)

How can I solve the problem? Is the globalize3 gem really compatible with Ruby on Rails 4? Is it advisable to wait for upgrading to Ruby on Rails 4?

Note: I seen the #415 Upgrading to Rails 4 railscast and I made many searches on the Internet (the most reasonable discussion is "Globalize3 does not work with Rails4") about the problem, but I am still in trouble.

回答1:

The globalize3 gem has been renamed globalize and major version numbers now correspond to the corresponding version of ActiveRecord (3.x for AR3 and 4.x for AR4).

So all you need to do is put this in your Gemfile, and you should not get any conflict:

gem 'globalize', '~> 4.0.0.alpha.2'

See also the github repository for more details.

回答2:

Try using rails4 branch to avoid upgrading issue.

gem 'globalize3', git: 'https://github.com/svenfuchs/globalize3.git', branch: 'rails4'

However, you may still meet some issues, because it's not stable branch.
