Pip version: 9.0.3

When I want to update pip with the command python -m pip install --upgrade pip aborts and I get the following error:

I followed this link Error while upgrading to pip 7.1.10 on Windows 8.1 (python 2.7)

easy_install -U pip

Solved broken dependencies and it worked for me

You should consider upgrading via the ‘pip install --upgrade pip’ command.

I had this issue as well… it seems various combinations of PATH and environment mangling can do this. Strangely I was able to upgrade this way:

python3 -m venv venv
. venv/bin/activate
pip install --upgrade pip

which upgraded my system pip from 9.x to 10.0.1. i’d love to be able to explain why that worked but ¯_(ツ)_/¯

I also experienced the same issue. The below later worked for me: #Windows 10: pip upgrade from 9.0.1 to 10.0.1 (base) C:\XXXXXXXX>conda update pip (base) C:\XXXXXXXX>conda update -n base conda (base) C:\XXXXXXXX>conda create -n my_root --clone=“C:\ProgramData\Anaconda3” (base) C:\XXXXXXXX>conda activate my_root

#Tensorflow installation (my_root) C:\XXXXXXXX> (my_root) C:\XXXXXXXX>pip install tensorflow (my_root) C:\XXXXXXXX>python -m pip install --upgrade pip

Just performed “python -m pip uninstall pip” first, then “python -m pip install -U pip”

So I have… C:\GITHUB\stress_testing\venv\Scripts\python.exe: No module named pip
