我正在编写一个程序，将视频分成帧，并使用opencv-python和pytesseract提取每n帧的文本。我设法使代码工作，但程序工作得相当慢。我尝试使用PyPy3来提高性能，但在为pypy安装opencv库时遇到了一个问题。
这是错误代码:

note: This error originates from a subprocess, and is likely not a problem with pip.

我觉得我什么都试过了。我使用
成功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wheels升级到最新版本了。
其他相关信息:
解释器路径:/usr/local/bin/pypy3
Python版本:PyPy 7.3.9 [Python 3.7.13]
操作系统:MacOS
我所理解的是，错误在于构建轮子，我读了一些关于自己构建包的东西。我也想不明白。如有任何帮助，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时，而不是引发ERROR, cmd被卡在Building wheel for opencv-python (pyproject.toml) ... |
错误提示可能链接到cmake，您可以尝试安装它。→https://cmake.org/install/
