# MRE for uv: https://github.com/pimlock/uv-bug-reproDescriptionThis is the upstream version of astral-sh/uv#17645. When a user has both typer and typer-slim in their dependency tree, one will overwrite the other, with the consequence that uninstalling one will partially uninstall the other. This is a problem with both pip and uv. Python package management doesn't support packages overlapping, depending on the installer it may even lead to corrupted files (parallel writing to the same files). Since a dependency tree may include both typer and typer-slim, those conflicts can happen silently, leading to hard-to-debug package management errors that only show up as runtime crashes. I read #786 but unfortunately I don't follow why both packages include the same files, instead of only one package. More of a meta comment, but I was surprised there is no dedicated bug reporting option, but only the funnel into the question flow.

Issue to track this is here: #1503 (yes the process is a bit convoluted, but we otherwise get too many "bug reports" that really aren't bugs, so this way we try to manage the issue tracker a bit) |

Thanks for porting this over
It's not the discussion process (I see that you want to keep the issues actionable for the project), it's that I got a bit alienated by the discussion form implying I'm asking for help and should participate in the forum, when I was trying to upstream something causing problems for typer users that I had investigated and minimized. |

Yep, I agree that's not very inviting for reporting bugs/issues 😕 |

Thanks for the feedback! It's definitely not targetted at you, but trying to push people to try and come and help if they want to get free support, which is what happens most of the cases. 😅 Let me think about that part, maybe it can be rephrased. Also, I added some more context on why |

@tiangolo upgrading to 0.22.0 seems broken (only install from scratch works). Steps to reproduce:
Log: Due to this install/upgrade order - typer folder is gone, same module not found problem after tgat. (Note: can't drop typer-slim altogether, as it's a transient dependency via spacy) |

Thanks for the note! Yep, this is sadly "expected" and there's not an easy workaround. 😔 More details: The installer (poetry in this case, but could happen with pip, uv, etc) doesn't have a predefined order in which to remove old files and copy new files. What happened here is that it:
The end result, after removing and copying the Strangely, it could happen that it did the process in the other order, starting with And sadly, it would not be solvable by doing anything else that creates a new release, as the same would happen (only once). The next version installed (or installing from scratch) would work as normally, but the first time it is installed from the old version that provided files to any of the new ones that don't provide any files will have this (terrible) effect. I'm sorry for that, there's not much that can be done really, other than re-installing, or doing a sequence of upgrading to one version and then upgrading to the next. |

Thanks for the reply @tiangolo, with 0.23.0 the following works for me as a workaround to fix an env. Downgrade to 0.22.0 and upgrade back: |

typer-slimdoesn't provide any code, and only depends ontyper. 🚀
