我正在尝试在Windows Server 2003上安装Redmine 2.1.4.为了工作,我需要安装activerecord-mysql-adaptergem,而这似乎依赖于它mysql-2.9.0.gem.我从rubygems下载后者并执行:
gem install mysql-2.9.0.gem
它给出了以下输出:
C:\>gem install mysql-2.9.0.gem
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing mysql-2.9.0.gem:

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 …
