cannot load such file — mysql2/2.4/mysql2 (LoadErr

Question

I am new on Ruby on Rails. My Ruby version is ruby 2.4.1p111 (2017-03-22 revision 58053) [x64-mingw32].

I have created a new project using rails new sample_cms -d mysql command.

The command rails server is throwing following error.

C:/Ruby24-x64/lib/ruby/gems/2.4.0/gems/mysql2-0.4.6-x64-mingw32/lib/mysql2/mysql2.rb:2:in `require': cannot load such file -- mysql2/2.4/mysql2 (LoadError)

I have installed mysql and mysql Connector C. I have installed the mysql2 gem like that.

gem install mysql2 —platform=ruby — ‘—with-mysql-dir="C:\Program Files\MySQL\MySQL Connector C 6.1"’

I have uninstall and install the mysql2 gem but still facing the issue. Here is the directory which may have issue.

Here is the gem file entry for mysql2

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '~> 5.1.1'
# Use mysql as the database for Active Record
gem 'mysql2', '>= 0.3.18', '< 0.5'
# Use Puma as the app server
gem 'puma', '~> 3.7'

Any Help?

Answer 1

There is no mysql2 binary for Ruby 2.4 for Windows available at this time. So i uninstall ruby 2.4 and install ruby 2.3. Now it is working well
