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

An error occurred while installing mysql2 (0.3.16), and Bundler cannot continue

Make sure that `gem install mysql2 -v '0.3.16'` succeeds before bundling.

make的时候需要调用ruby很多编译前的参数.一些信息make不知道的话会不知道如何建库.
我个人的建议是根据你安装的ruby路径和版本信息把配置选项补充全.下面是我电脑上面的配置,你可以借鉴一下.据我分析应该能解决你的问题.
Provided configuration options:
--with-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/usr/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir
--ruby=/usr/local/ruby-2.1.2/rubies/ruby-2.1.2/bin/ruby

追问

我昨天已经解决，不过还是同样感谢
