python安装不上mesonpy库

安装scipy库时失败提示缺少mesonpy库。但又安装不上mesonpy库，提示缺少文件错误

FileNotFoundError: [Errno 2] No such file or directory: 'requirements.txt'

ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.
WARNING: You are using pip version 20.2.4; however, version 22.3 is available.
You should consider upgrading via the 'F:\python\python.exe -m pip install --upgrade pip' command.

没有搜索到mesonpy库安装失败是什么情况，求解答

报错说找不到你这个依赖库txt的文件呀
实在不行直接pip一个个装吧！
