Issue installing pythreejs 2.0.2 using conda on Ubuntu 18.04 - No module named 'TypedTuple'

[tpaviot]

On an up-to-date Ubuntu 18.4 machine, using conda fails installing latest pythreejs release:

$ conda create -n tst_py3js python=3.6
$ source activate tst_py3js
$ conda install -c conda-forge pythreejs=2.0.2
[...]

LinkError: post-link script failed for package conda-forge::pythreejs-2.0.2-py36_1000
running your command again with `-v` will provide additional information

My guess is that the recipe for pythreejs should be updated to use a more modern ipywidgets. A workaround is to install the most recent ipywidgets first.
