I have never used poetry... Mostly I just use conda or plain python envs. Never had those problems like you mention. When using anaconda in the stable channel you'll get a straight-forward "conservative" distribution of all the data science/numerical packages (and more). That's why people often say "just use anaconda", it really is quite simple as long as you don't mess up your stable environments with exotic packages you just want to try out. And it works well on Windows. No idea about Mac and don't care. Python doesn't need "something like deno". All programming languages need package management.
