active_record 5.1 pointing to earlier version?

I have upgraded a rails application to Rails 5.1 and see a strange issue.

When I check the mysql2_adapter.rb for the active_record gem I that the top 3 Line are

require "active_record/connection_adapters/abstract_mysql_adapter"
require "active_record/connection_adapters/mysql/database_statements"

gem "mysql2", ">= 0.3.18", "< 0.5"

however when I check the active_record gem on GitHub for the version 5.1 I see that the lines are different

https://github.com/rails/rails/blob/5-1-stable/activerecord/lib/active_record/connection_adapters/mysql2_adapter.rb


require "active_record/connection_adapters/abstract_mysql_adapter"
require "active_record/connection_adapters/mysql/database_statements"

gem "mysql2", ">= 0.3.18", "< 0.6.0"

Can anyone please help as to why the active_record 5.1 on my local machine has different code compared to what's on GitHub.

may be I missed something during rails upgrade.

Solution

  • The version you see on Github was the outcome of this pull request being merged on 2018-03-18. After that date, only Ruby on Rails 5.1.6 and 5.1.7 were released.

    But when I look at the stack trace of your question from yesterday, it feels like you are running Ruby on Rails 5.1.0.

    That means your Ruby on Rails version is about one year older than the latest Ruby on Rails 5.1.x version on GitHub.

    I suggest updating your Rails version at least to 5.1.7 by adding

    gem 'rails', '~> 5.1.7'

    to your Gemfile and then running bundle install again.
