gem install：无法构建gem原生扩展名（无法找到头文件） [英] gem install: Failed to build gem native extension (can't find header files)

问题描述

我使用的是Fedora 14，我安装并运行了MySQL和MySQL服务器5.1.42。
现在我试图以root用户身份执行此操作：

  gem install mysql 
  

但是我得到这个错误：

 构建原生扩展。这可能需要一段时间... 
错误：安装mysql时出错：
错误：无法构建gem本机扩展。 
 
 / usr / bin / ruby​​ extconf.rb 
 mkmf.rb在/usr/lib/ruby/ruby.h找不到头文件
 
 
 Gem文件将保留安装在/usr/lib/ruby/gems/1.8/gems/mysql-2.8.1中进行检查。 
结果记录到/usr/lib/ruby/gems/1.8/gems/mysql-2.8.1/ext/mysql_api/gem_make.out 
  

这里有什么问题？在安装红宝石1.8.7。和最新的rubygems 1.3.7。

解决方案

对于那些可能被接受的答案困惑的人，我也是，你也是需要安装ruby头文件[ ruby​​-devel ]。

保存我的皮肤的文章是 here 。

这是修改后的解决方案（请注意，我在Fedora 13上）：

  yum  - 安装gcc mysql-devel ruby​​-devel ruby​​gems 
 gem install -y mysql  -  --with-mysql-config = / usr / bin / mysql_config 
   
 $ b 
对于使用Debian风格的包装的Debian和其他发行版，安装ruby开发头文件为： 
 
 
  sudo apt-get install ruby​​-dev 
  
对于Ubuntu，ruby开发头文件是通过以下方式安装： 
 
 
  sudo apt-get install ruby​​-all-dev 
  
 
 
 
如果您使用的是早期版本的ruby（如2.2），那么您需要运行：
  sudo apt-get install ruby​​2.2-dev 
  
（其中2.2是你想要的Ruby版本）
 
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
But I get this error:
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
What's wrong here? In installed ruby 1.8.7. and the latest rubygems 1.3.7.
解决方案
For those who may be confused by the accepted answer, as I was, you also need to have the ruby headers installed [ruby-devel].

The article that saved my hide is here.

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
For Debian, and other distributions using Debian style packaging the ruby development headers are installed by:
sudo apt-get install ruby-dev
For Ubuntu  the ruby development headers are installed by:
sudo apt-get install ruby-all-dev
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
(where 2.2 is your desired Ruby version)
