Any tricks about upgrading pydal? I use sudo -H pip install pydal on MacOS. What about Windows?

Writing a kind of FAQ for py4web, and I'm lagging in my Python best practices. As near as I can tell getting the latest pydal just requires this on MacOS:

# -H ensures root HOME directory is used
sudo -H pip install pydal

Is that correct? Should I omit the -H?

And would it look like this on Windows 10?

pip install pydal

python3 -m pip install -U pydal

-U does the upgrade

THANKS TONS! Can do a better job on the grid eval. My 2018 MacBook Pro killed itself early yesterday and I am picking up the pieces of my broken life

One problem I have all the time is that while in python2 every py version (2.6, 2.7,…) keeps its own version of the libraries, in python3 this is not always the case. So libraries can be put in places that are shared between 3.6, 3.7, 3.8, etc. This means when I upgrade I some times I have to uninstall from all of them, and the specify what I want:

sudo python3.6 -m pip uninstall pydal

sudo python3.7 -m pip uninstall pydal

sudo python3.8 -m pip uninstall pydal

and they install the one I want:

python3.8 -m pip install -U pydal

Some times I had to uninstall twice for it to work. Never had these problems with python2.7.

For py4web specific packages requisites I am doing:

pip install -r requirements.txt

After git pull from py4web repo it will install/upgrade all needs.

I recommend instead of “pip …” you do “python3.7 -m pip …” so you specify which pip. You may have more than one.

Is there anything "magically special" about Python 3.7 for Py4Web? I am using 3.6.9 on Ubuntu 18.04 LTS (which is maintained through 2023). It seemed to be good enough with Py4Web.
