I'm new with RoR and I'm trying to install Mysql2 -v '0.3.11'. I have OS X Mountain Lion, rails 3.2.6 ,ruby 1.9.3.

Below is the error I get. I looked everywhere and didn't find anything.

$gem install mysql2 -v '0.3.11'

I too get same type of error in mac10.10 and used below commands that work for me:

  1. Install and upgrade Homebrew using:

    brew install mysql

  2. run Install Mysql gem file using:

    gem install mysql2 -v '0.3.11'

  3. Run bundle install

You're using RVM instead of the Ruby that comes with 10.8. Good. Now, stop using the MySQL that comes with 10.8.

Install and update Homebrew. Now run

brew install mysql

Use the /Gemfile in your project to install the mysql2 gem. Add

gem "mysql2"

to your /Gemfile. Then update your application with Bundler by running

bundle install

Let the package managers (Homebrew and Bundler) work for you.

This should fix the issues you're having.

As Deefour said, I had to use RVM. Answer goes to him, I just couldn't comment on his answer. +1

But rvm exec bundle install gave me an error:

rvm do bundle install was removed, use rvm 1.9.2,1.9.3 do bundle install or rvm all do bundle install instead.

I used sudo rvm all do bundle install and it all went flawlessly from then on.
