Hm, that's strange. I have used Pipenv and Poetry years ago, to reproducibly build data science environments that people used to learn about data science and data analysis. I don't think you can call that "toy projects". I guess you just had bad luck with some specific dependencies. What I do remember though is, that Poetry had far fewer problems than Pipenv had. Pipenv was still a fight, though I won every time one way or another.
