当出现此错误时，一般通过直接搜索该错误，其他指南给出的解决办法不一定适用于自己的情况。需要根据报错内容中具体的error找到解决方案。

个人报错情况如下

Building wheels for collected packages: pycocotools
  Building wheel for pycocotools (pyproject.toml) ... error

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for pycocotools
Failed to build pycocotools
ERROR: Could not build wheels for pycocotools, which is required to install pyproject.toml-based projects

 根本错误在于Microsoft Visual C++ 14.0 or greater is required.

解决方法

重新安装c++的各个版本没有用，即便我的电脑上有了最新版还是会报错。

所以最终安装了visual studio c++的生成工具（不用安装全部的vs c++）。
