PyPy3不会安装OpenCV

Question

我正在编写一个程序，将视频分割成帧，并使用opencv-python和pytesseract提取每个第n帧的文本。我设法使代码正常工作，但程序运行得相当慢。我试图使用PyPy3来提高性能，但遇到了一个问题:安装pypy的opencv库。

这是错误代码：

我觉得我什么都试过了。我成功地安装了所有其他依赖项

pypy3 -m pip install [package]

是的，我已经把我的pip，setuptools和轮子升级到了最新的版本。

任何其他有关资料：

解释器路径：/usr/local/bin/pypy3

Python：PyPy 7.3.9 [Python 3.7.13]

OS: MacOS

我所理解的是，错误在于制造车轮，我自己读到了一些关于构建包的内容。我想不出来了。任何帮助都将不胜感激。

编辑：

我使用brew install cmake安装了cmake。现在，当我尝试安装opencv-python，而不是引发错误时，cmd会被困在

错误消息声明它可能被链接到cmake，您可以尝试安装它。-> https://cmake.org/install/
