Rails動作確認

Ruby Mac

前回のとおりRubyをバージョンアップしてRailsを使おうとしたが，下記のようなエラーで動かず．

!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql.
MissingSourceFile (no such file to load -- mysql):
    /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
    /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require'
    /Library/Ruby/Gems/1.8/gems/activesupport-2.2.2/lib/active_support/dependencies.rb:153:in `require'
...(略)

gemでRuby用のmysqlを入れなければならないみたい．
まずは，portで入れたRubyと，デフォルトで入っているRubyGemsが混在しているのがイヤなので修正．
Railsも入れなおす．

% sudo port install rb-rubygems
% sudo gem install rails --include-dependencies

% which gem
/opt/local/bin/gem

% which rails
/opt/local/bin/rails

修正してから同じようにアクセスすると，エラーメッセージが短かくなった．

!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql.
127.0.0.1 - - [31/Dec/2008:12:33:22 JST] "GET /contact/hello/ HTTP/1.1" 500 14203
- -> /contact/hello/


下記のように入れなおすも上手くいかず．

% sudo gem install mysql --include-dependencies
ERROR:  Error installing mysql:
	ERROR: Failed to build gem native extension.

/opt/local/bin/ruby extconf.rb install mysql --include-dependencies
checking for mysql_query() in -lmysqlclient... no
checking for main() in -lm... yes
...(略)

色々調べた結果，ここの通りやるとうまくいった．

% sudo gem install mysql -- --with-mysql-config=/opt/local/lib/mysql5/bin/mysql_config
% gem list
..
mysql (2.7)
