Hi all,
I have installed Python 3.7.7 on Windows 10 and I understood that pip came
installed. However when I try using pip I get an unrecognised command error.
I tried following the instructions on this website:
https://docs.python.org/3/installing/index.html
However usage of pip as described at this website receives an unrecognised
command error. I have also tried adding the python directory to the Path
variable and running commands in the Python directory.
I have also tried this website without success:

Installation � pip 20.0.2

Warning. Be cautious if you are using a Python install that is managed by your
operating system or another package manager. get-pip.py does not coordinate
with those tools, and may leave your system in an inconsistent state.

Can I please have step by step instructions that have been verified to work
with Windows 10 and Python 3.7.7 that list all requirements, dependencies and
processes to install and run pip and then install libraries such as numpy and
pillow.
I don't know about numpy but pillow on Windows is a pain because it is
only available as source and pip want's to compile it. That is the pain.
Pip needs to use a C compiler and Windows was never designed to make
life easy for developers out of the box. You need to set up a dev
environment yourself for that. HOWEVER all is not lost ...
Visit https://www.lfd.uci.edu/~gohlke/pythonlibs/ which is Christoph
Gohlke's page of pre-compiled binaries for Windows. I couldn't use
Windows without it. That man deserves a Nobel prize for generosity.
You will find a suitable Pillow installer there. To install all you do
is execute it in the venv. But there is a better way if you need to
install it only in particular venvs.
Use pip!
If you download the Pillow installer to your Windows downloads
directory, here is a pip install incantation which works for me in an
activated venv ...
python -m pip install
D:\Users\mike/downloads/Pillow-6.0.0-cp37-cp37m-win_amd64.whl
Don't worry about my slashes and backslashes. That part of the above
line is copied from a requirements file assembled by batch file. Pip
doesn't care about the angle of the slash.
I think numpy people use Anaconda to install stuff. Not sure about that.
Good luck
Mike
Any help would be greatly appreciated.
