我对rails开发完全不熟悉，并且在过去一个月里一直在努力安装mysql2。我有Windows 8.1 64位，ruby 2.0.0p535 64位，rails 4.0.2，我有mysql2（0.3.14）64位。我从cmd得到的错误在下面。
C:\Users\tghol_000>gem install mysql2 --platform=ruby -- '--with-mysql-dir="C:\mysql-connector\"' --with-mysql lib="C:\mysql-connector\lib"'

Building native extensions with: '--with-mysql-dir="C:\mysql-connector\" --with-mysql-lib=C:\mysql- connector\lib'
