无法在 Windows 中安装 Pillow

Question

安装过程需要 zlib，我什至从 Github 安装并克隆了它。我是新手。

错误信息：

Answer 1

错误消息底部的 URL 表示：

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

我会尝试这样做，以避免依赖性问题，例如您运行遇到的问题。

编辑：pillow 只支持 Pillow >= 2.0.0 < 3.5.0 不支持 3.6.0

编辑：希望这项工作可行，我无法在 Windows 上进行实际测试。

Answer 2

在 Windows，你最好使用预编译的二进制文件（轮子）而不是从源代码构建。

Python 3.6.0 最终版将于本周晚些时候在 2016-12-23 发布，Pillow 尚不支持它。希望它能在 2017 年 1 月 1 日的下一个季度版本中得到支持。

不过，与此同时，您可以从这里下载一个非官方的 wheel，然后 pip install filename.whl

Answer 3

使用：

easy_install pillow

pip 无法正常工作

Answer 4

我最近在 Cygwin 的 Python3.6 下安装了 Pillow 并且需要以下软件包：

gcc-core
libjpeg-devel
zlib-devel
python3-devel
python3-setuptools（到运行easy-install-3.6）

我还安装了 pip 使用：

easy-install-3.6 install pip

然后最后：

pip3 install pillow

成功。

Answer 5

您可以尝试使用其 Windows 安装程序包安装 Pillow。
检查 https://pypi.org/project/Pillow/#files、Windows 安装程序包位于页面底部。
为我工作 Python 3.7.

Answer 6

在 windows 中，由于框架问题，一些软件包无法运行。同样可以通过 3rd 方站点下载和使用它。

Unofficial python Binaries

选择相应的版本下载相同的

然后例如，

pip install Downloads\Pillow.whl

现在安装不会出错

Answer 7

根据 docs:

python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow

您可能需要将 python3 替换为 py、py3 或 python，具体取决于您的安装。

使用普通的旧 pip install Pillow 对我不起作用，easy_install Pillow 也不起作用，它抱怨说 EasyInstall 无法安全地安装它。

Answer 8

pip install wheel
pip install Pillow

为我工作
