click install packaging toolerror description

I am very new to python and pycharm
I was unable to install pip amd pip packages in pycharm community version on windows
I run pip install cowsay,
prompt error pip install cowsay ^^^^^^^ SyntaxError: invalid syntax

I have been reading similar questions and anwsers on stackoverflow
I tried the official troubleshooting hereto add interpreter in pycahrm setting but i can only find python3 as interpreter, cannot find pip related file to be added as interpreter
I also tried this post’s method “/questions/74393492/pip-install-cmd-but-modules-not-found-in-pycharm”, it prompt error as SyntaxError.

even tried this method, it would not work

also tried sudo apt install python3-pip, prompt error as SyntaxError: invalid syntax

I figured it could be something wrong with my virtual environment but cannot find where to fix it.
