Question

我刚刚在这个iMac和rubygems上安装了MAMP，但是当我运行时：

sudo gem install mysql - -with-mysql-config = / usr / local / mysql / bin / mysql_config

给了我

您是否在Mac OS X上安装了Xcode开发人员工具？如果没有，我会从那里开始。

您可以在此处下载：http://developer.apple.com/technologies/xcode.html

安装完毕后，请重试。

你需要mysql开发库来编译它。如果你在linux上，你可以使用“yum install mysql-devel”。不确定如何在Mac上安装它们，但尝试从这里下载连接器库： MySql Connector Downloads

您可能必须传入--with-mysql-libs选项以指向解压缩C库时的目录。希望这能指出你正确的方向。

或者您可以将库放在默认目录中：的/ usr / lib64下/ MySQL的
