gem install: 无法构建 gem 本机扩展(找不到头文件)

2021-11-20 00:00:00 ruby mysql rubygems

我使用的是 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

这里出了什么问题?在安装的 ruby​​ 1.8.7 中.以及最新的 ruby​​gems 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，您还需要安装 ruby​​ 标头 [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].

拯救我隐藏的文章是此处.

这是修改后的解决方案(请注意，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 开发头文件通过以下方式安装:

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 开发头文件通过以下方式安装:

For Ubuntu the ruby development headers are installed by:

sudo apt-get install ruby-all-dev

如果您使用的是较早版本的 ruby​​(例如 2.2)，则需要运行:

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)
