I tried it on the Internet

pipinstall-U setuptools

I’ve also tried to reload setup tools with the command. The problem remains

Finally, you can go to X:: – Python, lib, site packages, delete two related folders of setup tools and one of six-1.10.0, then re install setup tools, and then install PIP install requests [socks], and everything will be OK
