TypeError: __init__() got an unexpected keyword argument 'allowed_methods'

Thank you very much for your useful tools and I have been successfully exported notes from EVERNOTE as .enex.

However there seems to be some problems while I was importing .enex into NOTION. I was using command:
python -m enex2notion --token [my token_v2 number] --done-file note.txt noteBook.enex

And it turns out to be:
Traceback (most recent call last):

I am a junior on using PYTHON and I could only be sure that this is dealing with version, but I don't know how to solve it, so I came for some help.

I was doing this on windows10 on a personal laptop, and my PYTHON version is 3.8.5 on Anaconda. Thank you!

And one more thing, during the last time I install enex2notion, it told me these things below, but I am not sure whether it would help:
ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.
We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.
mythx-models 1.9.1 requires python-dateutil==2.8.1, but you'll have python-dateutil 2.8.2 which is incompatible.

You have a dependency version conflict. I would suggest you install enex2notion into a virtual environment.
