Vim-binding does not react

pococito commented 7 years ago

Summary

Hi, as a fellow vimmer - thanks for the extension, however - I cannot make it work and need help with debugging why.

Environment

[ ] Operating system : Debian 8.8 linux 3.16.0-4-amd64
[ ] Web browser : Debian Chromium 57.0.2987.98 and Firefox 45.9.0
[ ] Version or revision of Jupyter Notebook : Jupyter Notebook 5.0.0 Python 3.4.2
[ ] Revision of jupyter-vim-binding : commit d6e3886bfe4008215f8e8286d9c0dcdb26debce9

Behavior

Trying to get any vim extension functionality reaction: yy, p, F1

Expected

copy, paste, help...

Actual

no vim-like reaction

Step by step procedure

Start local Jupyter Notebook by jupyter notebook
Access http://localhost:8888/
Open any .ipynb notebook and try vim binding keys

What you have done to solve the issue

Tried on both chromium and firefox.
Tried reinstalling a couple times in various ways. Still can't make it work.
I did activate it separately from gui and using command line - finished 'ok'.
The nbextensions tab shows the extension is installed and active.

Remarks

Despite supposedly proper installation it does not work nor shows any error messages. I get a couple log messages though from 'jupyter notebook' stdout, probably unrelated:

[W 16:24:59.918 NotebookApp] server_extensions is deprecated, use nbserver_extensions

How do I debug this?

lambdalisue commented 7 years ago

Hum... Let me know the output of the javascript console in browser's develop tool.

It seems your jupyter installation has failed. Reinstall it in a fresh environment. I confirmed with the following

# Create a new fresh virtualenv
python3 -m venv .venv3
# Activate the env
source activate .venv3
# Install jupyter
pip install jupyter
# Create required directory in case (optional)
mkdir -p $(jupyter --data-dir)/nbextensions
# Clone the repository
cd $(jupyter --data-dir)/nbextensions
git clone https://github.com/lambdalisue/jupyter-vim-binding vim_binding
# Activate the extension
jupyter nbextension enable vim_binding/vim_binding

I did a fresh venv, reinstalled jupyter, cloned your repo and it still does not work. Both ipywidgets and widgetnbextension are (and were) installed.

(dupa) pawel@paweldebian:testpy$ pip list | egrep 'widg|jupy'

jupyter (1.0.0)

Hum... but it works well on my environment.....

In case, I re-opened it.

pococito commented 7 years ago

I just upgraded my linux distro and circumstantially it started working..

lambdalisue commented 7 years ago

Ok. Good to hear :-)

uduse commented 7 years ago

I had a similar problem (Widgets are not available), but solved it using:

pip install ipywidgets
jupyter nbextension enable --py widgetsnbextension
