【问题描述】：
（顺便说一句，它告诉我我在这里有代码并且必须对其进行格式化，所以如果有什么看起来很奇怪，因为它不会让我发布它。）
在过去的两天里，我实际上已经重新安装了 3 次 Windows 8，并且实际上使用 Ubuntu 创建了双启动，这个问题令人沮丧。 （决定学习一个全新的操作系统比尝试修复 Windows 问题更烦人）
所以，总的来说，我是编码新手，但我一直在玩 ruby 和 rails 并决定尝试让数据库工作正常，每次遇到相同类型的问题时，这似乎是某种 windows 64 位 MySQL ruby 版本混淆。
我正在使用 Windows 6.1 64 和 ruby 2.0.0p353 (2013-11-22) [x64-mingw32] rails 4.0.2 和 MySQL 5.6
I've installed the devkit and did the test using ruby -rubygems -e "require 'json'; puts JSON.load('[42]').inspect" and it returned 42 and that whole installation seemed to go fine.
rails installed ruby 已安装，所有 -v 显示我列出的版本。
现在当我去安装 MySQL gem 时，它给了我这个。
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.

*** 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.
I read up and tried doing this after installing the MySQL c connector. And it returns as follows.
C:\Users\ryan>gem install mysql2 --platform=ruby -- '--with-mysql-dir="C:/mysql-
connector-c-6.1.3-win32/"'

I have devoted days to this problem, and reinstalled more things than I care to admit. Does anyone have any ideas how I could possibly fix this... ?
好的，这就是它现在吐出来的东西..
C:\Users\ryan>gem install mysql --platform=ruby --with-mysql-dir=c:\mysql-con 连接器-c-6.1.3-win32 暂时增强 PATH 以包含 DevKit... 使用以下命令构建本机扩展：'--with-mysql-dir=c:\mysql-connector-c-6.1.3-wi n32' 这可能需要一段时间... 错误：安装mysql时出错： 错误：无法构建 gem 原生扩展。

提供的配置选项： --with-opt-dir --without-opt-dir --with-opt-include --without-opt-include=${opt-dir}/include --with-opt-lib --without-opt-lib=${opt-dir}/lib --with-make-prog --没有-make-prog --srcdir=。 --curdir --ruby=C:/Ruby200-x64/bin/ruby --with-mysql-dir --with-mysql-include --without-mysql-include=${mysql-dir}/include --with-mysql-lib --without-mysql-lib=${mysql-dir}/ --with-libmysqllib --without-libmysqllib
Gem 文件将继续安装在 C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/mysql -2.9.1 进行检查。 结果记录到 C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/mysql-2.9.1/ext/mysql_ api/gem_make.out
