RoR3和MySQL错误：dyld：找不到符号：_mysql_init

我正在为Ruby on Rails 3.0.5应用程序Mac OS X 10.6解决MySQL问题.

我安装了MysqL 5.1版,但出现此错误：

dyld: lazy symbol binding Failed: Symbol not found: _MysqL_init
  Referenced from: /Users/manny/.gem/ruby/1.8/gems/MysqL2-0.2.6/lib/MysqL2/MysqL2.bundle
  Expected in: flat namespace

dyld: Symbol not found: _MysqL_init
  Referenced from: /Users/manny/.gem/ruby/1.8/gems/MysqL2-0.2.6/lib/MysqL2/MysqL2.bundle
  Expected in: flat namespace

Trace/BPT trap

我尝试安装MysqL v5.5,但仍然出现错误.我从.dmg安装了MysqL.

解决方法:

您不需要删除MysqL并重新安装它,我只需使用以下命令即可.在终端上执行此操作非常简单,它将解决您的问题：

rvmsudo ARCHFLAGS="-arch x86_64" gem install MysqL2 -- --with-MysqL-config=/usr/local/MysqL/bin/MysqL_config --with-opt-lib=/usr/local/MysqL/lib 

我希望这可以帮助您解决问题.
