Question

这是我的堆栈：

RHEL 5.8 x86_64
MySQL 5.5 x86_64
Ruby 1.9.3p345
Rails 3.2.8

我正在通过bundler安装mysql2 0.3.11 gem并得到错误，问题似乎与Ruby gem mysql2 install failing和mysql2 gem installation fails的常见错误不一样。这些是我已经为mysql安装的软件包。

[user@local config]$ yum list installed | grep MySQL

MySQL-client.x86_64                   5.5.29-1.rhel5                   installed

libdbi-dbd-mysql.x86_64               0.8.1a-1.2.2                     installed

错误消息如下：

An error occurred while installing mysql2 (0.3.11), and Bundler cannot continue.

Answer 1

尝试使用

bundle config build.mysql2 --with-mysql-config=/.../mysql_config

或

sudo gem install mysql2 -- --with-mysql-config=/.../mysql_config

无法通过bundler在RHEL 5.8上安装mysql2 gem
