markdown.tpl template not found error thrown by jinja2

When I execute knowledge_repo add example_post.ipynb -p project/example_ipynb I am getting this exception.
I get this whether I explicitly provide the repo path or if it's in an environmental variable. Tried on both Linux and Mac OS.

Traceback (most recent call last):

Hey Ian, have you made any progress with this? I've been stuck with the same issue for a couple of days and have not found a solution yet

I have yet to get over this hump!

Ok found a solution - downgrade nbconvert and nbformat:

pip uninstall nbconvert 
pip install  -Iv nbconvert==5.6.1

pip uninstall nbformat
pip install  -Iv nbformat==4.4.0 

(maybe work with other versions but the latest ones have this problem for sure)

Hi all, sorry about the delay. In the latest 0.9.0 release, the version of nbconvert and nbformat is pinned to below 6.0, which should resolve this issue. Please comment if you still run into problems with this.
