安装过程要求使用zlib，我什至从Github进行安装和克隆。我是这一切的新手。

错误消息底部的URL说：
Windows安装我们提供适用于Windows的Pillow二进制文件，该文件针对在Wheel，Egg和可执行安装程序中的32位和64位版本的受支持的Python矩阵进行了编译。这些二进制文件包括所有可选库：
pip安装枕头
我会尝试这样做，以避免遇到诸如您遇到的依赖性问题。
编辑：枕头仅支持枕头> = 2.0.0 <3.5.0而不是3.6.0
编辑：希望这项工作，我无法在Windows上进行实际测试。
用途：
easy_install pillow
点子不起作用
我最近在Cygwin的Python3.6下安装了Pillow，并需要以下软件包：
我还使用以下方法安装了pip：
easy-install-3.6 install pip
然后终于：
pip3 install pillow
成功。
在Windows上，最好使用预编译的二进制文件（转轮），而不是从源代码构建。
Python 3.6.0 final将于本周晚些时候在2016-12-23上发布，并且Pillow尚不支持它。希望它将在2017年1月1日的下一个季度版本中受支持。
但是，与此同时，您可以从此处下载一个非官方的轮子，然后通过pip install filename.whl安装
您可以尝试使用Windows Installer软件包安装Pillow。选中https://pypi.org/project/Pillow/#files，Windows Installer软件包在页面底部。使用Python 3.7为我工作。
在Windows中，由于框架问题，某些软件包无法使用。可以通过第三方网站下载和使用相同的软件包。
选择相应版本下载相同。
然后是例如
pip install Downloads\\Pillow.whl
现在它将安装而没有错误
