问题描述
我正在使用 Fedora 14，并且安装并运行了 MySQL 和 MySQL 服务器 5.1.42.现在我尝试以 root 用户身份执行此操作:
I am using Fedora 14 and I have MySQL and MySQL server 5.1.42 installed and running. Now I tried to do this as root user:
gem install mysql
但我收到此错误:
Building native extensions. This could take a while...
ERROR: Error installing mysql:
ERROR: Failed to build gem native extension.
/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /usr/lib/ruby/ruby.h
Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/mysql-2.8.1 for inspection.
Results logged to /usr/lib/ruby/gems/1.8/gems/mysql-2.8.1/ext/mysql_api/gem_make.out
这里有什么问题?在安装的 ruby 1.8.7 中.以及最新的 rubygems 1.3.7.
What's wrong here? In installed ruby 1.8.7. and the latest rubygems 1.3.7.
推荐答案
对于那些可能对接受的答案感到困惑的人，就像我一样，你还需要安装 ruby 头文件 [ruby-devel].
For those who may be confused by the accepted answer, as I was, you also need to have the ruby headers installed [ruby-devel].

这是修改后的解决方案(注意我使用的是 Fedora 13):
And this is the revised solution (note that I'm on Fedora 13):
yum -y install gcc mysql-devel ruby-devel rubygems
gem install -y mysql -- --with-mysql-config=/usr/bin/mysql_config
对于 Debian 和其他使用 Debian 风格打包的发行版，ruby 开发头文件由以下人员安装:
For Debian, and other distributions using Debian style packaging the ruby development headers are installed by:
sudo apt-get install ruby-dev
对于 Ubuntu，ruby 开发头文件由以下方式安装:
For Ubuntu the ruby development headers are installed by:
sudo apt-get install ruby-all-dev
如果您使用的是早期版本的 ruby(例如 2.2)，那么您将需要运行:
If you are using a earlier version of ruby (such as 2.2), then you will need to run:
sudo apt-get install ruby2.2-dev
(其中 2.2 是您想要的 Ruby 版本)
(where 2.2 is your desired Ruby version)
