如何在Mac OS 10.6上安装mysql gem？
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
给我

我怎么能安装这个gem？
我找到了这个并完美地完成了：
您可以访问http://www.tmtm.org/en/ruby/mysql/下载tar文件，然后运行以下命令
# ruby ./install.rb
安装mysql.rb
使用以下它与我合作
brew install mysql
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，再试一次。
我还是得到了这个

必要的库和/或标题。 检查mkmf.log文件以获取更多信息
细节。 您可能需要配置选项。
提供的配置选项：
–with-OPT-DIR
–without-OPT-DIR
–with-OPT-包括
–without-OPT-包括= $ {停用DIR} /包括
–with-OPT-LIB
–without-OPT-LIB = $ {选择-DIR} / lib目录
–with-MAKE-PROG
–without-MAKE-PROG
–srcdir =。
–curdir
–ruby = /系统/资源库/框架/ Ruby.framework /版本/ 1.8的/ usr / bin中/ruby
–with-mysql的，配置
Gem文件将保留在/Library/Ruby/Gems/1.8/gems/mysql-2.8.1中以供检查。
结果记录到/Library/Ruby/Gems/1.8/gems/mysql-2.8.1/ext/mysql_api/gem_make.out
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，但尝试从此处下载连接器库： 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：/ usr / lib64 / mysql
从mysql.com下载mysql-dev
