PlotlyJS/Orca.jl not installing properly

Hi all,

Had some bizarre issues with Julia lately so decided to start from scratch and freshly re-install Julia v1.2 and all packages. Mostly things are working again now but for some reason it seems the installation of PlotlyJS or Orca failed and I can’t figure out why.

When I select plotlyjs() back end, e.g.:

using Plots
...

plotlyjs()

I get this error:

Really not sure how to solve this issue. Any ideas?
Thanks!

Due to the problems with this ORCA.jl, we have decided to go another direction. The savefig functionality offered by ORCA.jl has been implemented by new routines built in to PlotlyBase.jl (and thus PlotlyJS.jl) itself.

ORCA.jl is now deprecated and should not be used going forward.

We will work with the Plots.jl team to get that integration set up

Thank you
