Ruby 1.9.3 と Mountain Lion で Ruby on Rails bundle install を実行できません。MySql2 gem はインストールされません。Mac OS X Lion に Ruby on Rails を約 10 回インストールしたので、手順はよく知っていますが、MySQL gem をインストールできません。これは私が得るエラーです。前もって感謝します。

bundle install --path mysql と bundle install --system を試しましたが、どちらも機能しませんでした

この男は同じ問題を抱えていました: mysql2 gem OS X Mountain Lion をインストールできません

mysql の brew バージョンを使用していますか?

rvm を使用していて、おそらく rvm の外部に mysql2 を追加した場合は、次の手順を試してください。

宝石「mysql2」

または Rails2.x の場合:

gem 'mysql2', '~> 0.2.11'

それから：

    $ cd RAILS_ROOT $ gem uninstall mysql2

    Select gem to uninstall:
     1. mysql2-0.2.11
     2. mysql2-0.3.6
     3. All versions
    > 3 # select "All versions" 
$ rvm gemset install mysql2
 $ bundle install

これで、レールが適切に起動するはずです。
