錯誤：錯誤安裝MySQL：錯誤：未能建立寶石原生擴展

Question

我跟着「http://blog.mmediasys.com/2011/07/07/installing-mysql-on-windows-7-x64-and-using-ruby-with-it/」設置on Rails應用程序和MySQL服務器5.1

所以紅寶石之間的連接，當我安裝mysql的寶石具有以下命令：

gem install mysql --platform=ruby -- --with-mysql-dir=C:/mysql-connector-c-noinstall-6.0.2-win32 

所以我發現了以下錯誤日誌：

Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing mysql:
ERROR: Failed to build gem native extension.

C:/Ruby187/bin/ruby.exe extconf.rb --with-mysql-dir=C:/mysql-connector-c
