我正在尝试使用以下命令安装 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 ofnecessary libraries and/or headers.

有人遇到过同样的问题吗?我应该怎么做才能解决这个问题?谢谢!

最佳答案

我遇到了完全相同的问题。我在 OS X 10.6 上安装来自 dev.mysql.com 的最新 MySQL 5.1 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,在相同的命令提示符下(因为路径只针对该 session 发生更改),我使用以下命令安装了 gem:

sudo sudo env ARCHFLAGS="-arch x86_64" gem install dm-mysql-adapter

我知道这个问题已经有 3 个月了,但是这个页面是“无法在 osx 上安装 dm-mysql-adapter”的热门页面,希望这能帮助到一些人。
