作者:互联网
Windows XP. Ruby 1.9.2.安装了Rails. MySQL已安装.当我尝试运行gem install mysql2(或bundle install)时,我收到错误:
C:\ruby\cred2>gem install mysql2
Building native extensions. This could take a while...
ERROR: Error installing mysql2:
ERROR: Failed to build gem native extension.

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:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include

解决方法:
仅供记录:问题应该解决!
mysql2 gem v.0.2.6已经出局,有win32支持.
gem install mysql2现在没有问题(安装了DevKit).
