mysql2 gem安装失败 [英] mysql2 gem installation fails
问题描述
我的堆栈如下:
- CentOS 6.3
Installed MySQL 5.5 (followed steps at http://www.if-not-true-then-false.com/2010/install-mysql-on-fedora-centos-red-hat-rhel/ because yum still has MySQL 5.1 and if I try to yum install any mysql related package, it will of course break as yum will expect 5.1)
$> mysql --version 适用于Linux(x86_64)的mysql Ver 14.14 Distrib 5.5.27，使用readline 5.1

当我尝试安装mysql2 gem时，出现以下错误:
When I try to install mysql2 gem, I get following error:
$> gem install mysql2
Building native extensions. This could take a while...
ERROR: Error installing mysql2:
ERROR: Failed to build gem native extension.

-----
mysql.h is missing. please check your installation of mysql and try again.

*** extconf.rb failed ***
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
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib

Gem files will remain installed in /usr/local/rvm/gems/ruby-1.9.3-p194/gems/mysql2-0.3.11 for inspection.
Results logged to /usr/local/rvm/gems/ruby-1.9.3-p194/gems/mysql2- 0.3.11/ext/mysql2/gem_make.out
当我这样做
$> find / -name mysql.h
我什么也没得到
Mysql运行正常，我已经在其中创建了数据库和表，并且sql在运行时没有任何问题.
Mysql is running properly and I have already created db and tables in it and sql are running without any issue.
是否可以在堆栈中安装mysql2 gem?如果是这样，那么我有什么想法吗?
Is it possible to have mysql2 gem installed in my stack? If so then any idea what I am missing?
更新:我尝试yum install mysql-devel会引发错误，因为我
使用Remi存储库安装了mysql5.5.虽然百胜期待
mySql 5.1
UPDATE : I tried yum install mysql-devel it throws error because I
have mysql5.5 installed, using Remi repository. While Yum expects
mySql 5.1
推荐答案
我正在执行此工作:
wget http://cdn.mysql.com/Downloads/MySQL-5.5/MySQL-devel-5.5.27-1.el6.x86_64.rpm
rpm -Uvh MySQL-devel-5.5.27-1.el6.x86_64.rpm
gem install mysql
gem install mysql2
