ruby - 安装 dm-mysql-adapter 时出错

Question

我是 Ruby 的新手。我安装了 DataMapper 并且正在尝试安装 dm-mysql-adapter-1.0.2 gem 。但是当我尝试安装时，出现以下错误。我正在使用 ubuntu 操作系统。

vinoth@vinoth-laptop:~/Downloads$ gem install dm-mysql-adapter-1.0.2 -- --with-mysql-                    lib=/usr/lib/mysql -- --with-mysql-conf=/usr/bin/mysql

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
  -  ........


Gem files will remain installed in /home/vinoth/.gem/ruby/1.8/gems/do_mysql-0.10.2 for  inspection.
Results logged to /home/vinoth/.gem/ruby/1.8/gems/do_mysql-0.10.2/ext/do_mysql/gem_make.out

我错过了什么吗？

附加信息。

Ruby 版本:ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]

您需要安装 mysql 开发包:

sudo apt-get install libmysqlclient-dev

应该做的事
