Is `nb_conda` broken?

[ilanschnell]

I fixed the problem, and uploaded new (not empty) _nb_ext_conf packages.

Installation from defaults works as expected. 👍

Addition, when installing nb_conda from conda-forge inside foo, the extension functions as expected.

When doing: conda install -c conda-forge nb_conda in the root environment, the following is yielded:

The following NEW packages will be INSTALLED:

    nb_conda:         2.2.0-py36_0  conda-forge
    nb_conda_kernels: 2.1.0-py36_0  conda-forge

The following packages will be SUPERSEDED by a higher-priority channel:

    conda:            4.3.22-py36_0             --> 4.3.21-py36_1 conda-forge
    conda-env:        2.6.0-0                   --> 2.6.0-0       conda-forge

Which is not too bad I guess. Sub-optimal but OK. What do you think?

Can you try with:

# nb_conda_kernels
$PYTHON -m nb_conda_kernels.install --enable --prefix $PREFIX

# nb_conda
jupyter-nbextension enable nb_conda --py --sys-prefix
jupyter-serverextension enable nb_conda --py --sys-prefix

@ilan, I can verify the that I have the _nb_ext_conf package installed but not the conf files installed

$ conda list _nb_ext_conf
# packages in environment at /media/data/miniconda3/envs/test:
#
_nb_ext_conf              0.4.0                    py36_0  

And there is not config files for the extensions...

$ jupyter nbextension list
Known nbextensions:
  config dir: /media/data/miniconda3/envs/test/etc/jupyter/nbconfig
    notebook section
      jupyter-js-widgets/extension  enabled 
      - Validating: OK

and

(test) damian-S400CA :: /media/data/devel :: 
$ jupyter serverextension list

Yes, this is very strange. I can confirm that the new _nb_ext_conf packages do not include any config files. I will investigate the problem and try to fix it.

[drorata]

@damianavila I'm sorry, but I didn't understand what further input I can provide.

@ilanschnell Does it mean that now I can install nb_conda from the default channel?

[ilanschnell]

Yes, that's what it means. Please ensure that _nb_ext_cont 0.4.0 build 1 gets installed.

[drorata]

@ilanschnell How can I verify this?

[ilanschnell]

conda list _nb_ext_conf should display:

_nb_ext_conf              0.4.0                    py36_1

where, the 1 at the end is the important part.

[damianavila]

I have verified that upgrading _nb_ext_conf to the latest fixes the issue. Thanks @ilanschnell !
