我怎样才能让mysql2安装？

Question

我完全不熟悉rails开发，并且一直在努力在过去的一个月里安装mysql2。我有Windows 8.1 64位，红宝石2.0.0p535 64位，铁轨4.0.2，我有mysql2（0.3.14）64位。我从cmd得到的错误如下。

 
C:\Users\tghol_000>gem install mysql2 --platform=ruby -- '--with-mysql-dir="C:\mysql-connector\"' --with-mysql   lib="C:\mysql-connector\lib"' 
    Temporarily enhancing PATH to include DevKit... 
    Building native extensions with: '--with-mysql-dir="C:\mysql-connector\" --with-mysql-lib=C:\mysql- connector\lib' 
    This could take a while... 
    *** extconf.rb failed *** 
    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.

你已经得到不必要的撇号，我已经检查它在哪里，删除，然后再试一次。
