Failing during updating pip

[07pepa]

when uprgrading pip it fails ...
(probably because pip is in use)

it is recomended to upgrade pip with

python -m pip install --upgrade pip

so if you detect pip as outdated update it with this comand

that should fix it

I have never seen this behaviour.

Can you give more information about the setup (OS, python version, distribution, etc) and the error message?

[07pepa]

well OS is win10 python 3.7 (and seen in 3.8) distro.... window 10 err mesage... i will copy exact message but what i recal it was going out of pip itself maybe try update pip on windows?

when i reproduce this again i will attach msg

[defjaf]

Yes, please do. You can always explicitly downgrade and then try to run it again, if you want to test it.

I did clean install of python and i reprocuded it ( icluding repro steps)

Steps to reprocude from clean state

1. clean install of python 3 (3.8) (if reinstaling do not forget to clean C:\Program Files from python dirs like C:\Program Files\PythonXX where XX are numbers)
2. run any shell with admin priv ( i used powershell)

in shell:

1. pip install pip-upgrade-outdated ( must issue warning that pip is old and we should update via comand python -m pip install --upgrade pip)
2. pip_upgrade_outdated ( also happen with exe)
3. UnicodeDecodeError exeption thrown
4. nothing after pip is updated

however pip updates (updating pip from 19.2.3 to 19.3.1)

in my case setup tools supoosed to be updated also but exeption iterupted it
