使用ImageMagick进行Brew链接
安装： ostaptan：~ostap $ brew install imagemagick –disable-openmp –from-source
==> Downloading http://downloads.sf.net/project/machomebrew/mirror/ImageMagick-6.7.7-6.tar.bz2 Already downloaded: /Library/Caches/Homebrew/imagemagick-6.7.7-6.tar.bz2 ==> Patching patching file configure Hunk #1 succeeded at 32371 (offset 447 lines). ==> ./configure --disable-osx-universal-binary --without-perl --prefix=/usr/local/Cellar/imagemagick/6.7.7-6 --enable-shared --disable-static ==> make install Error: The linking step did not complete successfully The formula built, but is not symlinked into /usr/local You can try again using `brew link imagemagick' ==> Summary /usr/local/Cellar/imagemagick/6.7.7-6: 1388 files, 32M, built in 61 seconds 在安装中链接错误后链接：
ostaptan：wand ostap $ brew链接imagemagick
Linking /usr/local/Cellar/imagemagick/6.7.7-6... Error: Could not symlink file: /usr/local/Cellar/imagemagick/6.7.7-6/include/ImageMagick/wand/wand-view.h Target /usr/local/include/ImageMagick/wand/wand-view.h already exists. You may need to delete it. To force the link and delete this file, do: brew link -f formula_name To list all files that would be deleted: brew link -n formula_name
如何链接??? 该怎么办？？ 在任何地方找不到答案！
正如brew链接输出中所建议的那样，试试吧
brew link -f imagemagick
这应该清理/usr/local/include/ImageMagick/旧链接，然后链接完成安装所需的文件。
如果这不起作用，请检查您的用户是否有权写入/usr/local/include/ImageMagick/* 。
经过几个小时的尝试，对我有用的唯一事情是：
sudo brew link --overwrite imagemagick
（还需要将/usr/local/bin/brew设为root ）
Homebrew不再支持overwrite sudo命令。
sudo brew link --overwrite imagemagick
错误：以root身份运行Homebrew非常危险，不再受支持。 由于Homebrew不会删除安装权限，因此您将为所有构建脚本提供对系统的完全访问权限。
