【问题描述】：
我已按照 http://geryit.com/blog/2011/01/installing-mysql-with-rails-on-mac-os-x-snow-leopard/ 上的说明进行操作，包括通过 macport 安装 ruby。
每当我执行 gem install mysql 时，我都会收到以下错误
bash-3.2# gem install mysql
Building native extensions. This could take a while...
ERROR: Error installing mysql:

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
--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=/opt/local/bin/ruby
--with-mysql-config
--without-mysql-config
Gem files will remain installed in /opt/local/lib/ruby/gems/1.8/gems/mysql-2.8.1 for inspection.
Results logged to /opt/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/ext/mysql_api/gem_make.out
我该如何解决这个问题？我已经使用包文件 (.pkg) 安装了 32 位 mysql，而且我对 ruby 非常陌生......
美国东部时间 2011 年 4 月 26 日下午 5:11 更新
安装 RVM 并将 ruby 更新到 1.9.2
我还浏览了 cmets 上发布的链接。我做了locate mysql_config
结果是
/usr/local/mysql-5.1.56-osx10.6-x86/bin/mysql_config
/usr/local/mysql-5.1.56-osx10.6-x86/man/man1/mysql_config.1
因此，我尝试了
gem install mysql - -with-mysql-config=/usr/local/mysql-5.1.56-osx10.6-x86/bin/mysql_config
但它仍然不起作用......但是我确实得到了新的错误信息......

You have to install development tools first.

真的很想感谢那些评论的人......如果能提供更多帮助真的很感激......已经尝试安装该死的mysql 2天......
【问题讨论】：
-
"查看 mkmf.log 文件以获取更多详细信息。" - 你能提供从那里看起来“有趣”的部分吗？如果没有实际的错误消息，很难猜测。
-
在哪里可以找到 mkmf.log 文件？抱歉……这里非常新……
-
尝试
sudo apt-get install libmysqlclient-dev libmysqlclient16然后gem install mysql2。 -
@Zabba 这对我有用，谢谢 :)
