I installed Imagemagic (both 32 and 64 bits versions were tried) and then used pip to install wand, I also set the Magick_Home env. variable to imagemagic address but when I run
Traceback (most recent call last): File "<stdin>", line 1, in <module> File "c:\Anaconda2\lib\site-packages\wand\image.py", line 20, in <module> from .api import MagickPixelPacket, libc, libmagick, library File "c:\Anaconda2\lib\site-packages\wand\api.py", line 205, in <module> 'Try to install:\n ' + msg) ImportError: MagickWand shared library not found. You probably had not installed ImageMagick library. Try to install: http://docs.wand-py.org/en/latest/guide/install.html#install-imagemagick-on-windows
For those on mac and using homebrew, it seems like Wand doesn't support imagemagick 7 yet as mentioned in other answers.
There's a new brew formula for Imagemagick 6 which can be used to install the older version in the meanwhile:
brew install imagemagick@6
Create a symlink to this newly installed dylib file as mentioned in other answer to get things working.
ln -s /usr/local/Cellar/imagemagick@6/<your specific 6 version>/lib/libMagickWand-6.Q16.dylib /usr/local/lib/libMagickWand.dylib
Tested on Sierra and seems to be working fine.
