Pip3 doesn't seem to update between post<n> builds

General Discussion
#1

It looks like pip3 doesn’t consider a “post2” build to be a higher version number than a “post1” build: attempting to run “sudo -H pip3 install panda3d” with the “post1” build already installed produces the following message:
“Requirement already satisfied: panda3d in /usr/local/lib/python3.6/dist-packages”

Uninstalling Panda and then re-installing does, however, seem to then grab the “post2” build.

I don’t know whether I was updating incorrectly (I still don’t quite have the hang of pip, in all fairness), or, if this is an issue, whether there’s some other way of marking post<n> builds so that pip recognises them as updates. (Or even whether it’s something worth fixing.)

Still, I wanted to bring it to attention, in case it is indeed both fixable and worth fixing.

That’s an unfortunate downside of pip. You need to add the -U flag to update packages.

Aaah, I thought that I might be missing some option! I looked for a command keyword–something like “update” instead of “install”–but didn’t think to comb through the “dash-letter” options.

Thank you for so answering! :slight_smile:
