Posted on 2012-07-04

Ubuntu + Mysql5 + Rails3.2 に mysql2 をインストールしようとしてエラーが出た時の対処メモ。

環境

OS: Ubuntu 12.04 64bit
DB: MySQL 5.5.24-0ubuntu0.12.04.1
Ruby on Rails 3.2.6
Gem
- mysql2 0.3.11

mysql2 をインストールしようとしてエラー

mysql2 をインストールするため Gemfile に追記します。

Gemfile

1	gem 'mysql2'

いつも通り bundle install を実行するとエラーが発生して mysql2 がインストール出来ません。

Terminal
