在 Mac 上安装 Pillow 时出现 Zlib 错误

Question

我一直在尝试在我的 Mac（运行全新安装的 El Capitan 和 python 3.5）上安装模块 Pillow 一段时间了。使用 pip3 install Pillow，我收到一条错误消息，指出未找到 zlib，这导致安装中止。我已经安装了 Xcode，所以理论上 zlib 已经安装了，当我用 brew pip 安装它时仍然没有用（所以我卸载了）。它在到达这里之前工作正常：

知道它为什么出错以及我该如何修复它吗？

Answer 1

运行

$ xcode-select --install

似乎已经解决了我的问题。

Answer 2

对于 Mojave (10.14)，您可能还需要运行以下命令：

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

Answer 3

这就是我在 M1 mac for python 2.7.18 on Monterey 12.0.1 上的工作方式：

LDFLAGS="-L/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib" CFLAGS="-I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include" pip install Pillow

Successfully installed Pillow-6.2.2
