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.

这对我有用...

正如之前的答案所述:

$ brew remove imagemagick
$ brew install imagemagick --disable-openmp --build-from-source

我得到了 magicwand.sh :

$ mdfind MagickWand.h -->
/usr/local/Cellar/imagemagick/6.8.0-10/include/ImageMagick/wand/MagickWand.h

然后我取出除实际文件名之外的整个路径并添加 C_INCLUDE_PATH= 例如:

/usr/local/Cellar/imagemagick/6.8.0-10/include/ImageMagick/wand/
--->
C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.8.0-10/include/ImageMagick/

然后我寻找 MagickCore.pc

$ mdfind MagickCore.pc
/usr/local/Cellar/imagemagick/6.8.0-10/lib/pkgconfig/MagickCore.pc

和以前一样:

/usr/local/Cellar/imagemagick/6.8.0-10/lib/pkgconfig/
--->
PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.8.0-10/lib/pkgconfig/

然后我在 gem install 中使用了这两个路径:

$ sudo C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.8.0-10/include/ImageMagick/ PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.8.0-10/lib/pkgconfig/ gem install rmagick

经过数小时的研究，它终于奏效了。希望它可以帮助某人。
