Question

在过去3个月我面对这个问题时，我需要一个很大的帮助。

我正在使用windows 8机器。

我试图在ruby中安装rails。一切都取得了成功。

但在安装mysql gem时，我可能会遇到许多错误，我已经复制并粘贴在

下面

C:\Users\Mounarajan P A>gem install mysql
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.

Could not create Makefile due to some reason, probably lack of necessary

Answer 1

实际上，在安装本机扩展时，我们应该拥有本机开发库。对于ubuntu，它是libmysql2-dev，以同样的方式查找windows的dev lib并安装它。这可以解决你的问题

Answer 2

您的意思是使用mysql宝石吗？我认为mysql2现在是与mysql数据库一起使用的标准/推荐gem。

无论如何，此链接可能会帮助您安装它： Unable to install mysql2 gem on windows 7
