问题很简单,我的操作系统是win 7 x64,我安装了DevKit-tdm-32-4.5.2-20110712-1620-sfx.exe,它运行良好:

C:\DevKit>ruby dk.rb install
[INFO] Skipping existing gem override for 'C:/Ruby192'
[WARN] Skipping existing DevKit helper library for 'C:/Ruby192'

C:\DevKit>gem install rdiscount --platform=ruby
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
Successfully installed rdiscount-1.6.8

C:\DevKit>ruby -rubygems -e "require 'rdiscount'; puts RDiscount.new('**Hello Ru
byInstaller**').to_html"
<p><strong>Hello RubyInstaller</strong></p>

然后我就像这样安装mysql2:gem install mysql2 --platform=ruby

我遇到了以下问题:

gem install mysql2 --platform=ruby
Fetching: mysql2-0.3.10.gem (100%)

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:

        --without-mysql-lib=${mysql-dir}/lib
        --with-libmysqllib
        --without-libmysqllib


Gem files will remain installed in C:/Ruby192/lib/ruby/gems/1.9.1/gems/mysql2-0.
3.10 for inspection.

我该怎么办?

非常感谢!

找不到mysql。你安装了mysql吗?

for windows x86:
gem install mysql2 --platform=ruby -- '--with-mysql-lib="c:\Program Files\MySQL\MySQL Server 5.5\lib" --with-mysql-include="c:\Program Files\MySQL\MySQL Server 5.5\include"'

安装特定版本,例如v 0.3.10

gem install mysql2 -v '0.3.10' --platform=ruby -- '--with-mysql-lib="c:\Program Files\MySQL\MySQL Server 5.5\lib" --with-mysql-include="c:\Program Files\MySQL\MySQL Server 5.5\include"'

for windows x64

gem install mysql2 --platform=ruby -- '--with-mysql-lib="C:\Program Files (x86)\MySQL\MySQL Workbench CE 5.2.35" --with-mysql-include="c:\Program Files\MySQL\MySQL Server 5.5\include"'
