With markdown-3.4.1 there is now longer etree

markdown 2.6 works fine

@jonashrem This was fixed with this commit but the new version of the package was not pushed to PyPi yet, hence pip install --upgrade mdv will give you the unfixed version 1.7.4 while pip install --upgrade git+https://github.com/axiros/terminal_markdown_viewer will make it.
I opened a PR for solving this but it shall still be pushed to PyPi by the author.

@dhondta I'm still getting the same error after running the fixed command. The message seems to show that it's still installing 1.7.4

Defaulting to user installation because normal site-packages is not writeable

Using the argument to force reinstall helped me, at least. For further details about forcing the pip to reinstall the current version, see this StackOverflow page.

pip install --upgrade --force-reinstall git+https://github.com/axiros/terminal_markdown_viewer
