2 问题探索
首先，opencv较旧的python版本不需要进行滚轮编译，因此造成编译在
building wheel for opencv-python (pep 517)
处停止。为了防止因为pip版本较旧引起干扰，首先运行
pip install --upgrade pip
更新pip版本，接着再次安装
pip install opencv-python -i https://pypi.tuna.tsinghua.edu.cn/simple
接着大概率能解决building wheel for opencv-python (pep 517)，但是遇到新的现象，终端运行到下面指令时卡住
building wheel for opencv(pyproject.toml) ...
我们希望看看后端到底是什么情况，用--verbose运行安装命令跟踪安装过程，也可以检查安装的百分比

发现后端确实一直在运行，由于opencv体积较大，编译时间较长，导致不显示安装进度的化，前端出现假死现象，静静等待即可。
3 问题解决
更新pip版本
pip install --upgrade pip
显示安装进程
pip install opencv-python -i https://pypi.tuna.tsinghua.edu.cn/simple --verbose
等待安装完成
