how to fix Error with pip after 20 update - python-3.x

Question

I’m using Python 3.6.7 64x on windows 10.
Today after my updating (pip) I got this error when I’m trying to install any lib.
Traceback (most recent call last):
File "c:\users\admin\appdata\local\programs\python\python36\lib\runpy.py", line 193, in _run_module_as_main
"__main__", mod_spec)

from pip._internal.cli.req_command import RequirementCommand, with_cleanup
ImportError: cannot import name 'with_cleanup'
I tried to repair the installation but it didn’t help.
So please will you tell me what I can do to fix this problem!
With all respect!

Answer 1

I didn't get any answer for my question, and I still don't know how to solve the problem with the 20 update of pip.
but I found a way to make pip work again by using 'easy_install pip==19.3.1' in the cmd. and now i'm using the pip 19.3.1 and it works well.
hope this will help somebody!
