Can't install Pillow in Windows

问题

The installation process asks for zlib and I even setup & cloned it from Github. I'm new to all of this.

Error message:

回答1:

The URL at bottom of error message says:

Windows Installation We provide Pillow binaries for Windows compiled for the matrix of supported Pythons in both 32 and 64-bit versions in wheel, egg, and executable installers. These binaries have all of the optional libraries included:

pip install Pillow

I would try that, to avoid dependency problems such as you have run into.

edit: The pillow only support Pillow >= 2.0.0 < 3.5.0 and not 3.6.0

edit: Hopefully this work, I was not able to actually test on Windows.

回答2:

use:

easy_install pillow

pip doesn't work somehow

回答3:

I have recently installed Pillow under Cygwin's Python3.6 and needed following packages:

gcc-core
libjpeg-devel
zlib-devel
python3-devel
python3-setuptools (to run easy-install-3.6)

I have also installed pip using:

easy-install-3.6 install pip

Then finally:

pip3 install pillow

succeeded.

回答4:

On Windows, you're better off using precompiled binaries (wheels) than building from source.

Python 3.6.0 final is due out later this week on 2016-12-23 and Pillow does not yet support it. Hopefully it will be supported for the next quarterly release, on 1 January 2017.

However, in the meantime, you can download an unofficial wheel from here, then pip install filename.whl

回答5:

You can try installing Pillow with its Windows Installer package.
Check https://pypi.org/project/Pillow/#files, Windows Installer packages are at the bottom of the page.
Worked for me with Python 3.7.
