我正在尝试使用以下内容安装gem dm-mysql-adapter 命令:
gem install dm-mysql-adapter -- --with-mysql-config=/usr/bin/mysql
--with-mysql-lib=/usr/lib/mysql
得到了这个结果:
Building native extensions. This could take a while... ERROR: Error installing dm-mysql-adapter: ERROR: Failed to build gem native extension. /usr/local/bin/ruby extconf.rb --with-mysql-config=/usr/bin/mysql --with-mysql-lib=/usr/lib/mysql *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.

有没有人遇到同样的问题?我该怎么做才能解决这个问题? 谢谢!

我有同样的问题。我在OS X 10.6上使用dev.mysql.com的最新MySQL 5.1软件包。
无论如何,事实证明修复非常简单,我只需要将mysql bin目录添加到我的路径中:
$ export PATH=$PATH:/usr/local/mysql/bin
然后,从同一个命令提示符(因为该路径只更改了该会话的路径),我使用以下命令安装了gem:
sudo sudo env ARCHFLAGS="-arch x86_64" gem install dm-mysql-adapter
我很欣赏这个问题已经有3个月了,但是这个页面是'无法在osx上安装dm-mysql-adapter'的最佳选择,希望这会帮助别人。
