嗨，我未成功尝试在Ubuntu 10.04上安装MySQL Gem。
我尝试了以下命令：
sudo gem install mysql
sudo gem install mysql -- --with-mysql-config=/usr/bin/mysql_config
我收到以下消息：
Building native extensions. This could take a while...
ERROR: Error installing mysql:
ERROR: Failed to build gem native extension.

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.
Provided configuration options:
--with-opt-dir

--with-opt-include
--without-opt-include=${opt-dir}/include

Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/mysql-2.8.1 for inspection.

我在很多论坛上都读过，安装MySQL客户端库（libmysqlclient-dev）可以解决上述问题，但对我而言确实如此。
apt-get install libmysqlclient15-dev

Note, selecting libmysqlclient-dev instead of libmysqlclient15-dev
libmysqlclient-dev is already the newest version.
