Gem在Snow Leopard中安装mysql失败 [英] gem install mysql failure in Snow Leopard

问题描述

我在Snow Leopard中成功安装了MySql x86_64，并且Ruby和Ruby Gems似乎已正确安装：

 $其中mysql 
 / usr /本地/ mysql / bin / mysql 
 $哪个ruby 
 / usr / bin / ruby​​ 
 $哪个gem

 $ mysql

 $ ruby​​ -v 
红宝石1.8.7（2008-08-11 patchlevel 72）[universal -darwin10.0] 
 $ gem -v 
 1.3.5 
 

不幸的是，我安装mysql gem时出错：

 $ sudo gem update --system 
 ... 
 $ sudo env ARCHFLAGS = -  arch x86_64gem install mysql -  --with-mysql-config = / usr / local / mysql / bin / mysql_config

解决方案

安装与Snow Leopard捆绑在一起的Xcode解决了这个问题。 b $ b

I successfully installed MySql x86_64 in Snow Leopard and Ruby and Ruby Gems seems to be installed properly:

$ which mysql
/usr/local/mysql/bin/mysql
$ which ruby
/usr/bin/ruby
$ which gem
/usr/bin/gem
$ mysql
Your MySQL connection id is 404
Server version: 5.1.37 MySQL Community Server (GPL)
$ ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0]
$ gem -v
1.3.5

Unfortunatly I get an error installing mysql gem:

$ sudo gem update --system
...
$ sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
Building native extensions.  This could take a while...
ERROR:  Error installing mysql:
    ERROR: Failed to build gem native extension.

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb --with-mysql-config=/usr/local/mysql/bin/mysql_config
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h


Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/mysql-2.8.1 for inspection.

解决方案

Installing the Xcode that's bundled with the Snow Leopard fixed the problem.
