无法在OS X 10.6 Snow Leopard Server上安装mysql gem

Question

在OS X Server 10.6上安装mysql ruby​​ gem时遇到问题。

这是我得到的错误：

macserver:~ admin$ sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-       config=/usr/bin/mysql_config

Building native extensions. This could take a while…

ERROR: Error installing mysql:
ERROR: Failed to build gem native extension.

/Users/admin/.rvm/rubies/ruby-1.8.7-p371/bin/ruby extconf.rb --with-mysql-config=/usr/bin/mysql_config

checking for mysql_ssl_set()… yes
checking for rb_str_set_len()… yes
checking for rb_thread_start_timer()… yes
checking for mysql.h… no

*** extconf.rb failed ***

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.

Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir
--ruby=/Users/admin/.rvm/rubies/ruby-1.8.7-p371/bin/ruby
--with-mysql-config

Gem files will remain installed in /Users/admin/.rvm/gems/ruby-1.8.7-p371/gems/mysql-2.9.1 for inspection.
Results logged to /Users/admin/.rvm/gems/ruby-1.8.7-p371/gems/mysql-2.9.1/ext/mysql_api/gem_make.out

任何帮助表示赞赏。

您需要安装MySQL的开发标头。 Oracle的默认二进制软件包不包括这些。

如果您使用的是Homebrew或MacPorts，则这两个都将能够提供所需的文件。
