ERROR: ImportError: cannot import name 'specs' from partially initialized module 'pylatexenc.latexwalker._defaultspecs' (most likely due to a circular import)

[jtplaarj]

Betterbib is giving me an error about a circular import.

The steps to reproduce it are:

python3 -m venv .venv
source .venv/bin/activate
pip3 install betterbib
betterbib up bib.bib

The contents of the bib file seem irrelevant. An example from the documentation

@article {krylov,
  author = {Liesen and Gaul and Nabben},
  title = {Framework Deflation Krylov Augmented}
}

The full error is:

Yeah, pylatexenc is a flaky dependency. Doesn't seem to be maintained upstream. Will plug in something else soon.

I just tried reproducing the issue but was unable to do so.

[jtplaarj]

True. The version giving the error was 4.2.0, with current version 4.3.3 everything seems OK.

Thanks!!!
