Since you are familiar with nodejs:
poetry == npm
pyenv == nvm
pipx == npx
No big difference, IMO.

Package Management - npm? bower? yarn? Which should I use this week?
Interpreter Versions - Revisiting a project I last touched 2 years ago on node 8 has a load of locked dependencies that only work on that node version. OK, let's bring in nvm so I can get a dev environment going.
Executable Packages - oh no I've got two different projects with different and incompatible versions of apollo, what do I do? Oh right, sure npx for executable isolation so we don't pollute the global namespace.
Every ecosystem has these problems, and if they don't it's probably because they're still relatively esoteric.
Exactly! I'm not aware of any non-compiled language where (all) these issues are solved much better. I can be very productive with the tools I mentioned above and I'm glad that they work almost identical for both my main drivers (Python and JS/TS).
