Installation fails with `UnsatisfiableError: The following specifications were found to be incompatible with each other`

See original GitHub issue

Following the instructions at https://holoviz.org/installation.html, at step 2 I’m getting:

I was able to successfully install this (prior to the rename to holoviz if it helps). Using Ubuntu 16.04, conda 4.7.5

I think there is something weird going on with the environment solver, I installed python=3.6 as directed first, but then followed that with installing numpy separate from holoviz, like so:

conda create -n holoviz-tutorial python=3.6 conda activate holoviz-tutorial conda install --override-channels -c pyviz -c conda-forge numpy=1.16 conda install --override-channels -c pyviz -c conda-forge holoviz

Then conda was able to successfully solve the environment.

I believe @jlstevens updated the pyviz channel’s phantomjs with the one from conda-forge, which should make it work the same with or without that channel. That doesn’t mean it’s the right thing to do, as presumably there was a reason it pinned fontconfig before, but at least it gets things working. Please reopen if you have any issues again.
