ruby-on-rails - rmagick 和 imagemagick bundle/Homebrew 程序错误

Question

请参阅下面的错误堆栈。我尝试通过 Homebrew 软件“gem pristine rmagick”卸载/安装 imagemagick，然后重新安装 rmagick。所有都返回了相同的错误。任何帮助将非常感激 - 现在已经有一段时间了。

$ gem install rmagick

Can't install RMagick 2.13.1. Can't find the ImageMagick library or one of the dependent libraries. Check the mkmf.log file for more detailed information.

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:

这是解决方案的简陋之处(rmagick 已损坏，您必须创建符号链接(symbolic link)才能使其正常工作):

cd /usr/local/Cellar/imagemagick/6.8.0-10/lib

ln -s libMagick++-Q8.7.dylib   libMagick++.dylib

ln -s libMagickCore-Q8.7.dylib libMagickCore.dylib

ln -s libMagickWand-Q8.7.dylib libMagickWand.dylib
