解决：

1.查看自己的python版本和需要下载的matplotlib版本

这里查看报错的第1行和第3行

 copying libmatplotlibmpl-datafontsttfSTIXGeneralBol.ttf -> buildlib.win-amd64-3.10matplotlibmpl-datafontsttf
 set buildlib.win-amd64-3.10matplotlib_version.py to '3.5.2'

得知python版本为3.10，matplotlib 版本为 3.5.2

2. 下载对应的版本的.whl 文件

地址：https://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib

我下载了  matplotlib-3.5.2-cp310-cp310-win_amd64.whl

再打开cmd，输入：

pip install matplotlib-3.5.2-cp310-cp310-win_amd64.whl

成功！
