Installing mysql2 gem on mac with RVM is real pain

Step 1:--

    rails s/usr/local/rvm/gems/ruby-1.9.2-p180/gems/mysql2-0.3.2/lib/mysql2.rb:8:in `require': dlopen(/usr/local/rvm/gems/ruby-1.9.2-p180/gems/mysql2-0.3.2/lib/mysql2/mysql2.bundle, 9): Library not loaded: libmysqlclient.16.dylib (LoadError)

    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

STEP 2:--

 sudo install_name_tool -change libmysqlclient.16.dylib /usr/local/mysql-5.5.9-osx10.6-x86_64/lib/libmysqlclient.16.dylib /usr/local/rvm/gems/ruby-1.9.2-p180/gems/mysql2-0.3.2/lib/mysql2/mysql2.bundle

rails sWARNING: This version of mysql2 (0.3.2) doesn't ship with the ActiveRecord adapter bundled anymore as it's now part of Rails 3.1 WARNING: Please use the 0.2.x releases if you plan on using it in Rails <= 3.0.x

MySql version '0.2.7' solved my issue.

 gem 'mysql2', '0.2.7'

The above problem occurs presently on EngineYard App Cloud with Ruby 1.9.2 and Rails 3.0.3. Using mysql 2.8.1 barfs b/c EY sets mysql2 adapter. Using mysql2 0.3.2 barfs. So I was seriously stumped. Props to Richard Soutar's answer. It worked.

Your stacktrace after Step 2 told you what to do:

Please install the mysql2 adapter: gem install activerecord-mysql2-adapter

Update

Also, upgrade your Rails to 3.0.7 - there are a number of security holes (and bugs) in 3.0.3.

Update

Looks like that error message from Rails is wrong, it should have read:

Please use the 0.2.x releases if you plan on using it in Rails <= 3.1

Ie. for anything less than 3.1 you need to pin mysql2 to the 0.2 release, and not allow it to use 0.3. To do this, change your mysql2 line in your Gemfile to this:

gem "mysql2", "~> 0.2"

Then re-run bundle install

I have the sam problem. What I did is doing;

gem install --version '0.2.7' mysql2

Then on your Rails's GemFile. Should look like this.

gem 'mysql2', '0.2.7'

Then try again. Hope it help.

Try this (but I cannot guarantee anything)

Check this post about how to
- remove MySQL 5.5.
- install MySQL 5.1 (I think I downloaded the 32bit DMG version)
Follow this post to create the GEM.

Hopefully it will work after this. I'll cross my fingers for you.
