Installing PIL (Python Imaging Library) in Win7 64 bits, Python 2.6.4

Question

I\'m trying to install said library for use with Python. I tried downloading the executable installer for Windows, which runs, but says it doesn\'t find a Python installatio

Answer 1

If you installed a win64 python, you need a win64 PIL. The official PIL download site only has win32, as far as I can tell. The win32 installer will not see your 64-bit python installation.

No amount of tinkering with permissions or redistributables will fix this. You could use the win32 python instead (the Win64 python is mutant anyhow; Microsoft decided that C 'long' should be 32 bits in their 64-bit world, so python 'ints' are only 32 bits in Win64 python).

Since sizeof(long)!=sizeof(ptr) in win64, porting C extensions can be problematic, and will not be the same as porting them to linux 64. E.g. it seems that Win64 numpy is experimental/broken whereas linux64 numpy has been fine for years. My recommendation is if you use win64, stick with win32 python. If you want 64-bit python use linux.

Answer 2

I've just had the same problem (with Python 2.7 and PIL for this versions, but the solution should work also for 2.6) and the way to solve it is to copy all the registry keys from:

HKEY_LOCAL_MACHINE\SOFTWARE\Python

to

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python

Worked for me

Answer 3

I found a working win7 binary here: Unofficial Windows Binaries for Python Extension Packages It's from Christoph Gohlke at UC Irvine. There are binaries for python 2.5, 2.6, 2.7 , 3.1 and 3.2 for both 32bit and 64 bit windows.

There are a whole lot of other compiled packages here, too.

Be sure to uninstall your old PILfirst. If you used easy_install: easy_install -mnX pil
And then remove the egg in python/Lib/site-packages

Be sure to remove any other failed attempts. I had moved the _image dll into Python*.*/DLLs and I had to remove it.

Answer 4

Just got this error msg on my 32 bit Windows - I read the FAQ here: http://pythonware.com/products/pil/faq.htm and this sort of indicates that Windows is funny. Looked again at install pg and downloaded the Windows executable for Python26 # Python Imaging Library 1.1.7 for Python 2.6 (Windows only) - and the _imaging module gets installed when you run this. Should solve problem. So you can't just do the python setup.py install routine on: Python Imaging Library 1.1.7 Source Kit (all platforms) (November 15, 2009).

press contrl F type Pillow‑2.4.0.win‑amd64‑py3.3.exe

then click and downloadd the 64 bit version

Pillow is a replacement for PIL, the Python Image Library, which provides image processing functionality and supports many file formats. Note: use from PIL import Image instead of import Image. PIL‑1.1.7.win‑amd64‑py2.5.exe PIL‑1.1.7.win32‑py2.5.exe Pillow‑2.4.0.win‑amd64‑py2.6.exe Pillow‑2.4.0.win‑amd64‑py2.7.exe Pillow‑2.4.0.win‑amd64‑py3.2.exe Pillow‑2.4.0.win‑amd64‑py3.3.exe Pillow‑2.4.0.win‑amd64‑py3.4.exe Pillow‑2.4.0.win32‑py2.6.exe Pillow‑2.4.0.win32‑py2.7.exe Pillow‑2.4.0.win32‑py3.2.exe Pillow‑2.4.0.win32‑py3.3.exe Pillow‑2.4.0.win32‑py3.4.exe

I was having the same problem so I decided to download the source kit and install it according to how you posted above...

1. Downloaded Source Kit
2. Opened command prompt on that folder and typed python setup.py build
3. Then I typed python setup.py install

It worked perfectly!

Now, some notes: when I typed python setup.py build, I saw that Microsoft Visual Studio v9.0 C compiler was being used to build everything.

So probably it's something with your compiler not correctly configured or something...

Anyways, that worked with me so thank you!
