ImageMagick wand not recognizing pdf image?

Question

I'm trying to use this blog post to convert one pdf to a jpg, however everytime I try to run this simple script I get this exception wand.exceptions.WandError: wand contains no images MagickWand-56' @ error/magick-image.c/MagickWriteImage/13001

from wand.image import Image

with Image(filename="myFile.pdf") as img:
    img.save(filename="myFile.png")

I'm using the latest version of Wand and Python 3.4.2. The only thing I can think of is possibly a version compatibility issue.

I just tested this example myself on Ubuntu 14.04 x64 and python 3.4.1 and it works. Are you sure "myFile.pdf" actually exists? maybe its wrong path or filename? — Marcin, Dec 30 '14 at 01:59
Yeah. I've used the full path, the relative and the filename. Same error. — BarFooBar, Dec 30 '14 at 02:05
Have you checked with different pdf? maybe this pdf is corrupted, or it is not an usual one (e.g. some security rules or something else). — Marcin, Dec 30 '14 at 02:13
maybe then some libraries missing. do you use linux/windows/mac? check what is required there for pdfs? ghostscript maybe? — Marcin, Dec 30 '14 at 02:17
That was it. Ran `brew install ghostscript` and it worked. Thanks! — BarFooBar, Dec 30 '14 at 02:23

So just to close the question, the problem is missing ghostscript library on mac, as indicated in my comment above:

In case this helps somebody else: I got the same error message, installed imagemagick with ghostscript bindings, reinstalled wand and *still* got the error along with a message complaining about X11. After I installed the latest XQuartz everything worked. This was on OS X 10.0.4 – Robin Jul 31 '15 at 14:28
