Wand ImageMagick无法在Eclipse中将PDF转换为PNG，但可以在Terminal中使用

Question

I have a very strange issue. I am trying to use the Wand ImageMagick binding for Python to convert a PDF to a PNG. I am running on Mac, installed ImageMagick with homebrew, and I have installed ghostscript and freetype, which are required for PDFs. I have the following code:

from wand.image import Image

img = Image(filename='/users/joelclark/Downloads/test.pdf')

img.save(filename='/users/joelclark/Downloads/test.png')

When I run this in Terminal using my python interpreter, it works great, the PNG file is generated. However if I run this same code in Eclipse, I get the following error:

Traceback (most recent call last):
  File "/Users/joelclark/Development/lims/mirage/test.py", line 11, in <module>
   img.save(filename='/users/joelclark/Downloads/test.png')
  File "/Users/joelclark/Development/lims/mirage-flask/flask/venv/lib/python2.7/site-packages/wand/image.py", line 2719, in save
    self.raise_exception()
  File "/Users/joelclark/Development/lims/mirage-flask/flask/venv/lib/python2.7/site-packages/wand/resource.py", line 222, in raise_exception
    raise e
wand.exceptions.WandError: wand contains no images `MagickWand-1' @ error/magick-image.c/MagickWriteImage/13115

Keep in mind that I am using the EXACT same interpreter in Eclipse that I am in Terminal. I have also verified that the Python environments are the same, environment variables are the same, etc. It seems like an issue with Eclipse, but I honestly just cannot tell. I have also tried modifying permissions with chmod. When I did this the number after 'MagickWand' in the stack trace would change. For example 'MagickWand-5' instead of 'MagickWand-1'. I have no idea what this could mean but I figured I should mention it. I read a similar post here Difference running python in PyCharm and in terminal but this was with PyCharm and not Eclipse. Any help would be greatly appreciated. If there is any more information I can provide please let me know.

I found the answer. My PATH in environment variable was not the same in Eclipse. It was missing the /usr/local/bin path.
