It seems that the dependencies of mkdocs and flake8 conflict, but why does pdm always drop the version of irrelevant dependencies? It was mypy before, this time it is isort. |

It is because The resolver only back jumps one step each time it encounters a conflict. For the optimization of this algorithm, you may be interested in sarugaku/resolvelib#113 |

Just because I changed mypy from pypi to git …… was I still using mypy 0.991 at the time I asked the question, that would cause mypy to keep downloading. |
