windows - 如何在 Windows 上安装 Pillow 依赖项(没有二进制文件)？

Question

我正在尝试在 Windows 10 上使用 Python3 在 vi​​rtualenv 中运行 django-cms。

如果我按照他们网站上的安装步骤并运行命令 djangocms mysite 然后我得到这个错误:

Please wait while I install dependencies

安装 PIL 时似乎缺少 libjpeg(用于 Pillow 中的 JPEG 支持)和 zlib(用于 Pillow 中的 PNG 支持)，但是是否有“简单”的方式在 Windows 上获取它们？禁用不是解决方案，因为它们是 django-cms 需要的...

也许 this解决方案会起作用，但对于 virtualenv，它不是一个很好的解决方法......

但是问题应该是可以解决的吧？ ;-)

您正在链接到旧版本的文档。最新版本https://pillow.readthedocs.io/en/4.1.1/installation.html说:

In general, we aim to support all current versions of Linux, macOS, and Windows.

但是:

We don’t recommend trying to build on Windows. It is a maze of twisty passages, mostly dead ends. There are build scripts and notes for the Windows build in the w i n b u i l d directory.

但是:

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

所以我建议你按照通常的方式使用pip安装。
