Macxia PIP3 command is not available due to Operation error

I want to uninstall pyenv need upgrade pip command from 9.0-->10.0 command wrong cause PIP3 command not available

The correct way to upgrade:sudo pip3 install--upgrade Pip Online said, did not authenticate themselves (because PIP3 has been hung)

At least Python3 command can also be used, will be https://bootstrap.pypa.io/get-pip.py content inside the URL (content more load time to see the end is if __main__ in copy)

Copy all paste to local file named get-pip.py

Install using the sudo python3 get-pip.py command
