Rails、MySQL和雪豹
Rails、MySQL和雪豹
提问于 2009-06-13 22:54:00
我用我们在WWDC得到的光盘升级到了雪豹。
现在尝试运行我的一些rails应用程序时遇到sql问题
(in /Users/coneybeare/Projects/Ambiance/ambiance-server)

sudo gem install mysql不工作，并给出错误：

将mysql重建为64位或安装64位版本很重要，但您还需要确保将mysql gem的本机部分也构建为64位(如果您使用的是原始的Intel Core Duo macs，则这一点不适用)。
下面是这个神奇的命令：
env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config无论何时在Snow Leopard上使用本地组件进行gem安装，都应该按照上面所示的方式设置ARCHFLAGS。

如果你使用的是bundler，你可以使用"bundle config“为mysql设置正确的构建参数，如下所示：
bundle config build.mysql --with-mysql-config=/usr/local/mysql/bin/mysql_configStack Overflow用户

我为此斗争了很长一段时间，最终在雪豹上让它工作了。我最终从源代码安装了Ruby、RubyGems和MySQL (请参阅安装Ruby和RubyGems的Hivelogic tutorial )。MySQL教程链接在底部)。我终于得到了gem的安装，但我还是得到了
dyld: lazy symbol binding failed: Symbol not found: _mysql_init
Referenced from: /Library/Ruby/Site/1.8/universal-darwin10.0/mysql.bundle
Expected in: flat namespace
dyld: Symbol not found: _mysql_init
Referenced from: /Library/Ruby/Site/1.8/universal-darwin10.0/mysql.bundle
Expected in: flat namespace
Trace/BPT trap我最终删除了mysql.bundle (我不知道这是做什么的)，这一切都起作用了。
sudo rm -f /Library/Ruby/Site/1.8/universal-darwin10.0/mysql.bundle希望这能帮助到一些人。
