Installation issues on Windows/Python 3.7

[Mattwmaster58]

What did you do?

Admin CMD console > python -m pip install pillow --trusted-host='pypi.python.org'

What versions of Pillow and Python are you using?

Python Version 3.7, latest pip
Latest Pillow version (4.3?)
Windows 10 Pro

I think the most relevant part from this error is this part:

The headers or library files could not be found for zlib,
 a required dependency when compiling Pillow from source.

and yet typing import zlib into the python console produces no errors.
Is it b/c the Appdata dir is c:\users\marcus family\appdata\local\ half the time and the other times it's C:\Users\MARCUS~1\AppData\Local\?

Here is the full output from python -m pip install pillow --trusted-host='pypi.python.org"

Here is the full output from this command

We don't yet officially support unreleased Python 3.7.

Because pip can't find a binary wheel for 3.7, it's downloading the source and trying to build it, which on Windows is a pain.

I suggest downloading the wheel for Python 3.6 and pip installing from that.

[hugovk]

The same thing came up for Python 3.6: #2318 and a few times on Stack Overflow, and will come up again.

Python 3.7 is still in alpha but due out on 2018-06-15:
https://www.python.org/dev/peps/pep-0537/#schedule

We'll most likely have wheels for Python 3.7 in our 2018-07-01 release (probably Pillow 4.6.0 5.2.0).

Before that, should we print out a warning for Python 3.7 on Windows that it's not yet supported and suggesting to use the 3.6 wheel? (And when 3.7 is supported, ++ each version.)

[Mattwmaster58]

Before that, should we print out a warning for Python 3.7 on Windows that it's not yet supported and suggesting to use the 3.6 wheel?

That would be helpful. I'll try the 3.6 wheel later today.

[Mattwmaster58]

Manually downloading the all variants of the 3.6 wheel have all rendered the same error message:
Pillow-4.3.0-[version specifc info].whl is not a supported wheel on this platform.

I go back to Python 3.6, I just like the bleeding edge (;

[hugovk]

#2855 is a PR to warn 3.7 isn't yet supported on Windows.

By the way, you may be able to install the 3.6 wheel on 3.7 by renaming it from Pillow-4.3.0-cp36-cp36m-win32.whl to something like Pillow-4.3.0-cp37-cp37m-win32.whl (https://stackoverflow.com/a/28111899/724176).

[cfleveratto]

I'm getting the same error for Pillow version 4.3.0 and python version 3.6.3 with final error of

Command "/usr/bin/python3 -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-yuztoa48/Pillow/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-3lhc0a5r-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-yuztoa48/Pillow/

[hugovk]

@cfleveratto That doesn't look like Windows or Python 3.7. Please open a new issue with more detail.
