問題：在Ubuntu7.10中，使用
Java代碼
sudo gem install mysql 

sudo gem install mysql
出現：
Java代碼
ERROR:  While executing gem ... (RuntimeError)  
    ERROR: Failed to build gem native extension.  
Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/mys 

ERROR:  While executing gem ... (RuntimeError)
    ERROR: Failed to build gem native extension.

解決方案
1.先運行
Java代碼
$ sudo apt-get install libmysqlclient15-dev 

$ sudo apt-get install libmysqlclient15-dev

注意上面安裝的庫名為libmysqlclient15-dev而非libmysqlclient5-dev

2.再運行
Java代碼
sudo gem install mysql
