I don't know how to install mysql2.

I'm using:

  • Ruby On Rails 3.2.14
  • Ruby 2.0.0
  • Mac OS X 10.9 ("Mavericks")
Installing mysql2 (0.3.13) 

An error occurred while installing mysql2 (0.3.13), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.13'` succeeds before bundling.

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

    /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby extconf.rb 

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.


Gem files will remain installed in /Users/kimingi/.bundler/tmp/1983/gems/mysql2-0.3.13 for inspection.

    Do you install the libmysqlclient-dev first? – Bigxiang Aug 20 '13 at 03:54
  • One of the problems with living on the bleeding edge of OS versions is you inherit the problems of porting existing code to work on the unknown/new code-base. Installers test for known versions and often vomit badly with unknown ones. – the Tin Man Aug 20 '13 at 04:14

You need to install mysql locally. Since you're on OS X you can use Homebrew.

# to Install homebrew
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"

# to install mysql through homebrew
brew install mysql

  • You might add more information about how to install homebrew since it's not a normal part of a Mac OS installation. – the Tin Man Aug 20 '13 at 04:15

I ran to the same problem. To fix this problem, open a command prompt. go to your application folder. And type: gem install mysql2 -v 0.3.11 this version is working great.
