To see why this extension failed to compile, please check the mkmf.log which can be found here:

  /home/fz/.rvm/gems/ruby-2.3.0/extensions/x86_64-linux/2.3.0/mysql-2.9.1/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /home/fz/.rvm/gems/ruby-2.3.0/gems/mysql-2.9.1 for inspection.
Results logged to /home/fz/.rvm/gems/ruby-2.3.0/extensions/x86_64-linux/2.3.0/mysql-2.9.1/gem_make.out

 出现这个错误，是因为少安装了一个lib， 执行

sudo apt-get install libmysqlclient-dev
