Question

那么有没有人能够在CentOS上成功运行Rails 3.2？这是我们看到的问题：

[root@scglobal-web01 current]# rails c
/var/www/html/webapps/intl-custserv/shared/bundle/ruby/1.9.1/gems/mysql2-0.3.11/lib/mysql2.rb:9:in `require': Incorrect MySQL client library version! This gem was compiled for 5.5.15 but the client library is 5.0.92. (RuntimeError)
    from /var/www/html/webapps/intl-custserv/shared/bundle/ruby/1.9.1/gems/mysql2-0.3.11/lib/mysql2.rb:9:in `<top (required)>'

这里有一些关于我们环境的详细信息：

[root@scglobal-web01 ~]# cat /etc/redhat-release
CentOS release 5.7 (Final)
[root@scglobal-web01 ~]# mysql --version
mysql  Ver 14.14 Distrib 5.5.13, for Linux (x86_64) using readline 5.1  
[root@scglobal-web01 ~]# rvm list

我遇到了同样的问题。

运行：

CentOS版本6.3（最终版）
mysql Ver 14.14使用readline 5.1为Linux（x86_64）分发5.5.28
rvm and ruby 1.9.3

到目前为止我所知道的是mysql-devel包是针对mysql 5.0.x而不是5.5

我需要使用新包重新安装gem。但到目前为止我无法做到这一点

迹象是

$ sudo yum install mysql-devel
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: centos.mirror.linuxwerk.com
 * epel: mirrors.n-ix.net
 * extras: mirror.jgotteswinter.com
 * updates: mirror.optimate-server.de
Setting up Install Process
Resolving Dependencies
--> Running transaction check
---> Package mysql-devel.x86_64 0:**5.1.69**-1.el6_4 will be installed

然后我们安装它。 bundle install适用于安装0.3.13。我们回到了：

$rails c
...../gems/mysql2-0.3.13/lib/mysql2.rb:8:in `require': Incorrect MySQL client library version! This gem was compiled for 5.1.69 but the client library is 5.5.28. (RuntimeError)

CentOS上的Rails 3 - mysql2 gem的问题？
