Opencv-contrib installation error: file not found

Question

这里有一个 Linux 新手。在 Linux Mint，python 3.8，在 Anaconda 下，尝试通过

安装 opencv-contrib-python

pip install --no-binary opencv-contrib-python opencv-contrib-python

经过漫长且非常耗费资源的过程后出现此错误。关于我缺少的东西有什么建议吗？作为旁注，没有 --no-binary 的正常 pip 安装工作正常，但会导致我试图根据 this post.[=13= 解决的运行时错误]
