Hi,

I tried to use ipymd now with python3 on my laptop but I got following error after starting notebook server on the http://localhost:8888/tree

Server error: Traceback (most recent call last): File "/home/arymanus/dev3/lib/python3.4/site-packages/notebook/base/handlers.py", line 436, in wrapper result = yield gen.maybe_future(method(self, *args, **kwargs)) File "/home/arymanus/dev3/lib/python3.4/site-packages/tornado/gen.py", line 1008, in run value = future.result() File "/home/arymanus/dev3/lib/python3.4/site-packages/tornado/concurrent.py", line 232, in result raise_exc_info(self._exc_info) File "<string>", line 3, in raise_exc_info File "/home/arymanus/dev3/lib/python3.4/site-packages/tornado/gen.py", line 282, in wrapper yielded = next(result) File "/home/arymanus/dev3/lib/python3.4/site-packages/notebook/services/contents/handlers.py", line 126, in get path=path, type=type, format=format, content=content, File "/home/arymanus/dev3/lib/python3.4/site-packages/ipymd/core/contents_manager.py", line 86, in get file_extension = format_manager().file_extension(self.format) File "/home/arymanus/dev3/lib/python3.4/site-packages/ipymd/core/format_manager.py", line 143, in file_extension return self._formats[name]['file_extension'] KeyError: 'markdown'

terminal errors are as following

@rossant, do you think that it might really be some bug or just problem with mine installation?

rossant commented 8 years ago

looks like you're missing some dependencies

[I 15:39:44.992 NotebookApp] ipymd format markdown could not be loaded: No module named 'yaml'
[I 15:39:45.006 NotebookApp] ipymd format atlas could not be loaded: No module named 'yaml'
[I 15:39:45.012 NotebookApp] ipymd format opendocument could not be loaded: The 'odfpy' distribution was not found and is required by the application
RafalSkolasinski commented 8 years ago

Yes, indeed installing yaml with

pip install pyyaml

is solving the problem.

Maybe it would be good idea to add it to ipymd dependencies?

Thanks!

Okay, I did it. I hope it's okay. Sorry for not linking PR to this issue, I didn't know how to do it. I think this issue may be closed.
