Error: 'InlineHtml' is not defined. Fresh install of present, unable to get it working with sample.md

Describe the bug After installation, I receive the following error when attempting to perform present sample.md.

Traceback (most recent call last):

NameError: name 'InlineHtml' is not defined

I am unable to use the present command on any markdown file, as I get the same error every time.

Steps to reproduce the bug Steps used to install present:

1. pip install present seemed to work with no issues

Steps to reproduce the behavior:

1. On a MacOS, simply use pip install present, then git clone <repo> and cd /examples, then run present sample.md.
2. It does not work, and results in the error listed above

Expected behavior Well, hopefully the default slideshow should run. I'm thinking there is some dependency that is not installed? But I cannot figure out what it is--I am new to python, I apologize.

Slides I am using the included sample.md file.

Environment

• OS: MacOS
• Terminal: iTerm2
• Python version: 3.9.9
• present version: the latest (installed today). I cannot find specific version number as present --version is not an option. Sorry!
