Python：无法在 Pypy3.7 (7.3.1) 上安装 Pillow 库

Question

Pillow 似乎没有安装在 Pypy3.7 上。我在 Mac OS Catalina 10.15.4 上运行它。

Pip3 install Pillow

返回：

 
    During handling of the above exception, another exception occurred:
    
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/private/var/folders/sg/g7xccd2d5ql7cv01qg_3j0440000gn/T/pip-install-6bmk1_j2/pillow/setup.py", line 918, in <module>
        raise RequiredDependencyException(msg)
    RequiredDependencyException:
    
    The headers or library files could not be found for zlib,
    a required dependency when compiling Pillow from source.
    
    Please see the install instructions at:
       https://pillow.readthedocs.io/en/latest/installation.html

这里有什么我遗漏的吗？我所看到的只是缺少的“Zlib”。我试过了

brew install Zlib

并重新安装 Xcode 以防万一。似乎没有任何效果。奇怪的是它适用于 python3 pip，但不适用于 pypy3 pip。

尝试更改 CPATH：

export CPATH=`xcrun --show-sdk-path`/usr/include
