Ruby连接Mysql数据库

已经尝试连接Mysql数据库好久了,都没有连接成功.

Mac OS 10.5.2,
Mysql 5.0.45
Ruby 1.8.6

下载了ruby-dbi

按照Readme上面的方法,已经显示安装成功了

Brinados-iMac:ruby-dbi brinado$ ruby setup.rb config --with=dbi,dbd_mysql
entering config phase...
config done.

Brinados-iMac:ruby-dbi brinado$ ruby setup.rb setup
entering setup phase...

setup.rb: skip ext/dbd_sqlite(dbd_sqlite) by user option
setup.rb: skip ext/dbd_sybase(dbd_sybase) by user option
setup done.

setup.rb: skip ext/dbd_sqlite(dbd_sqlite) by user option
setup.rb: skip ext/dbd_sybase(dbd_sybase) by user option
install done.

在运行很简单的测试文件时提出了错误,

RubyMate r8136 running Ruby r1.8.6 (/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby)
>>> basic_figure.rb

DBI::InterfaceError: Could not load driver (no such file to load — mysql)

method load_driver in dbi.rb at line 344
method _get_full_driver in dbi.rb at line 227
method connect in dbi.rb at line 213
at top level in basic_figure.rb at line 3
Program exited.

后来又尝试安装mysql-ruby-2.7.5,总是提示说

can't find header files for ruby.

Ruby连接Mysql数据库应该是很主流的阿,为什么这样费劲呢?[img]../../../images/smiles/icon_twisted.gif" alt="[/img]
不知道我的问题在哪里?希望得到大家帮助!

P.S. 如何安装ruby-devel? 安装又出现错误~~

Brinados-iMac:~ brinado$ gem install ruby-devel
ERROR:  could not find ruby-devel locally or in a repository
