【中文标题】gem mysql2未安装在rails上的ruby上[重复]

【英文标题】：gem mysql2 not installed on ruby on rails [duplicate]

【发布时间】：2014-02-15 04:07:29

【问题描述】：

我安装了以下版本：

ruby 1.9.3p484 (2013-11-22) [i386-mingw32] 导轨 4.0.2 DevKit-tdm-32-4.5.2-20111229-1559-sfx rubygems-2.1.11 mysql 服务器 5.6 mysql-connector-c-noinstall-6.0.2-win32-vs2005

我已经运行了以下三个命令：

$ gem i mysql2

$ gem install mysql2 -- '--with-mysql-lib="C:\Program Files\MySQL\MySQL Server 5.6\lib" --with-mysql-include="C:\Program Files\MySQL\MySQL Server 5.6\include" --with-mysql-dir="C:\Program Files\MySQL\MySQL Server 5.6"'

$ gem install mysql2 --platform=ruby -- '--with-mysql-lib="C:\mysql-connector-c-noinstall-6.0.2-win32-vs2005\lib" --with-mysql-include="C:\mysql-connector-c-noinstall-6.0.2-win32-vs2005\include" --with-mysql-dir="C:\mysql-connector-c-noinstall-6.0.2-win32-vs2005"'

以上三个cmds有以下错误：

* 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.

【参考方案1】：

sudo apt-get install libmysql-ruby libmysqlclient-dev
