ImageMagick 7 が悪いのだ?
上記エラーに wand/MagickWand.h
が無いとあります。
/usr/local/Cellar/imagemagick/7.0.6-7/include/ImageMagick-7
を見ればわかりますが、ImageMagick 7 からは、ディレクトリ wand
が MagickWand
に変更になったようなのです。
僕あソースをあまりいじりたくないので、ImageMagick 6 にダウングレードすることにしました。

==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have this software first in your PATH run:
echo 'export PATH="/usr/local/opt/imagemagick@6/bin:$PATH"' >> ~/.zshrc
For compilers to find this software you may need to set:
LDFLAGS: -L/usr/local/opt/imagemagick@6/lib
CPPFLAGS: -I/usr/local/opt/imagemagick@6/include
For pkg-config to find this software you may need to set:
PKG_CONFIG_PATH: /usr/local/opt/imagemagick@6/lib/pkgconfig
