mysql - gem mysql2 未安装在 ruby on rails 上

<分区>

我安装了以下版本:

ruby 1.9.3p484 (2013-11-22) [i386-mingw32]
rails 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"'

以上三个命令有以下错误:

* 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.

最佳答案

sudo apt-get install libmysql-ruby libmysqlclient-dev
