  markdown-it-py~=0.6.0 (from jupytext==1.10.3->jupyter-book==0.11.1->-r requirements.txt (line 1))

Expected behavior

I expected a consistent set of pinned dependencies that I could store in a requirements.txt file.

Environment

Python 3.8.6 on Pop OS 20.04

well, as you can see lol, its also frustrating for me, since I have gone to great pains to ensure all the dependency pieces fit together 🥴. But yeh come v0.12, this should all clear up, and then the point of releasing markdown-it-py v1 was that it should be pretty stable now and rarely incur any further breaking changes.

Just FYI, this problem also arises when using pipenv to manage a project’s environment. I have worked around it with direct, restricted dependency on mdit-py-plugins:

[packages]
jupyter-book = "==0.11.*"
mdit-py-plugins = "<0.2.7"
