PIL Image ImportError

I have Pillow and qrcode modules installed in a virtual environment.

From the python shell, I can create a test image programmatically using PIL:

>>> from PIL import Image
>>> img = Image.new('1', (200, 200))
>>> img.save('test-image.jpeg', 'JPEG')

Great, that works just as I would expect it to. However, I'm getting this error when I try to use a module that relies on PIL:

>>> import qrcode
>>> qr_code = qrcode.make("1") 
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "/home/vagrant/.virtualenvs/env1/local/lib/python2.7/site-packages/qrcode/main.py", line 8, in make
     return qr.make_image()
   File "/home/vagrant/.virtualenvs/env1/local/lib/python2.7/site-packages/qrcode/main.py", line 186, in make_image
     from qrcode.image.pil import PilImage
   File "/home/vagrant/.virtualenvs/env1/local/lib/python2.7/site-packages/qrcode/image/pil.py", line 5, in <module>
     import Image
ImportError: No module named Image

Why can't qrcode import PIL's Image class but it works from the shell?

This is a bit of a shot in the dark, but… does from PIL import ImageDraw also work on the shell? If that module is somehow missing from the PIL package, qrcode will assume Image is also missing from the PIL package and try to import it from the top level, which will cause exactly the problem you're seeing. – abarnert
A more likely possibility is that you're not actually testing from the right virtual environment. From your shell, after that from PIL import Image, just type Image and see what path it gives you. Is it inside /home/vagrant/.virtualenvs/env1/blah/blah, or not? – abarnert

This is an issue with your installation: Image module have been installed as subpackage of a PIL module, while the library you are using expects Image module to be directly in the python path. Simplest solution is to replace:

import Image

with:

from PIL import Image

in file qrcode/image/pil.py.
