使用 32 位 Python 在 Windows 上安装 Pillow

Question

我在运行 pip installpillow 时收到此错误。

在处理上述异常的过程中，又发生了一个异常：

注意：此错误源自子进程，并且可能不是 pip 的问题。
错误：枕头搭建轮失败
制作枕头失败
错误：无法为枕头构建轮子，这是安装基于 pyproject.toml 的项目所必需的
警告：检查 pip 的最新版本时出错。

我升级了pip。现在我正在从 C:\Python39-32\lib\site-packages\pip (python 3.9) 运行 pip 23.3。

Answer 1

您似乎安装了 32 位版本的 Python。从 Pillow 10 开始，不再提供预编译的 32 位轮子：

https://pillow.readthedocs.io/en/stable/releasenotes/10.0.0.html#bit-wheels

pip 因此尝试从源代码构建，并且您没有必要的依赖项。

选项：

• 安装 64 位版本的 Python：https://www.python.org/downloads/windows/
• 安装

  pillow<10

• 安装依赖项以从源代码构建：https://pillow.readthedocs.io/en/stable/installation.html#building-from-source

Answer 2

与

配合良好

Python: 3.11.4
Pip 23.2.1
pillow: 9.5.0
