Rails的 - 无法运行，因为“libMagickCore.5.dylib”的rake命令

Question

当我运行run rake db:create，我得到这个错误说法：

rake aborted! 
dlopen(/Users/adam/.rvm/gems/ruby-1.9.3-p327/gems/rmagick-2.13.1/lib/RMagick2.bundle, 9): Library not loaded: /usr/local/lib/libjpeg.8.dylib

我花了整个下午在寻找一个问题，如何解决它，但没有成功。

有问题的部分是在这里：

Referenced from: /usr/local/opt/imagemagick/lib/libMagickCore.5.dylib 
    Reason: Incompatible library version: libMagickCore.5.dylib requires version 13.0.0 or later, but libjpeg.8.dylib provides version 12.0.0 - /Users/adam/.rvm/gems/ruby-1.9.3-p327/gems/rmagick-2.13.1/lib/RMagick2.bundle 

我怎样才能在OS X Lion的升级libMagickCore.5.dylib？

预先感谢您

编辑：重新安装imagemagick后，我跑了rake db:create，并得到：

Answer 1

我在过去类似的问题，简单地跑了操作系统上的软件更新和开发人员工具。

如果不解决这个问题，你也可以尝试删除并重新安装运行与自制imagemagic：

brew update 
brew remove imagemagick 
brew install imagemagick 

Answer 2

在命令行尝试gem pristine rmagick。
