为 ruby​​ 安装 mysql gem

Question

我在安装 mysql gem 时遇到问题：

gem install mysql

Fetching: mysql-2.8.1.gem (100%)
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
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir
--ruby=/home/user/.rvm/rubies/ruby-1.9.2-p290/bin/ruby
--with-mysql-config
--without-mysql-config
--with-mysql-dir
--without-mysql-dir
--with-mysql-include
--without-mysql-include=${mysql-dir}/include
--with-mysql-lib
--without-mysql-lib=${mysql-dir}/lib
--with-mysqlclientlib
--without-mysqlclientlib
--with-mlib
--without-mlib
--with-mysqlclientlib
--without-mysqlclientlib
--with-zlib
--without-zlib
--with-mysqlclientlib
--without-mysqlclientlib
--with-socketlib
--without-socketlib
--with-mysqlclientlib
--without-mysqlclientlib
--with-nsllib
--without-nsllib
--with-mysqlclientlib
--without-mysqlclientlib
--with-mygcclib
--without-mygcclib
--with-mysqlclientlib
--without-mysqlclientlib

mkmf.log 文件包含大量对我没有帮助的 gcc 调试输出，我可以发布它，但我敢打赌，它会像提到的配置选项一样简单。

有没有人在 Ubuntu1104 系统上有过这方面的经验？

感谢任何提示！

干杯， 马克

显然您还没有安装编译此 gem 所需的 MySQL 开发库。 libmysqlclient-dev 可能会有所帮助。
