 Gem文件将保持安装在C：/Ruby200-x64/lib/ruby/gems/2.0.0/gems/mysql 
 2-0.3.14中进行检查。 
记录到C的结果：/Ruby200-x64/lib/ruby/gems/2.0.0/gems/mysql2-0.3.14/ext/mysq

解决方案
从here 。然后将其复制到C盘的根目录以方便访问，这样您的连接器文件夹路径将如下所示： 
 
 
  C ：\mysql-connector-c-6.1.3-win32\ 
  
现在复制这一行代码到您的cmd并执行（请记住更改您的连接器版本号）
  gem install mysql2 --platform = ruby - '--with-mysql-dir =C：/mysql-connector-c-6.1.3-win32/'
  
经过很长时间的尝试，我以这种方式成功安装了32位和64位Windows 7中的mysql2 gem。干杯！

 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.

解决方案
Download the 32-bit Zip Archive of connector from here. Then copy it at the root of your C drive for ease of access so that your connector folder path will be something like this 
C:\mysql-connector-c-6.1.3-win32\
Now copy this line of code to your cmd and execute (remember to change the connector version number with your one)
gem install mysql2 --platform=ruby -- '--with-mysql-dir="C:/mysql-connector-c-6.1.3-win32/"'
After trying for a long time I successfully installed mysql2 gem in both of my 32 and 64 bit windows 7 in this way. Cheers!
