PlotlyJS does not display plot and errors on `Pkg.test("PlotlyJS")`

General Usage

This is the first time I use the package PlotlyJS. test PlotlyJS opens an empty window and outputs errors.

This is using Julia 1.5.4 on Windows 10.

There is something wrong with the artifacts downloaded by the most recent release of PlotlyJS. For a temporary fix, feel free to try whether

julia>]add https://github.com/jonas-kr/PlotlyJS.jl

fixes the issue on your system.

Thank you, the tests pass and a canvas open and displays the plot.

While adding the package from your repository, I got the following error, which didn’t prevent PlotlyJS to pass the tests.

Great! (Un)fortunately, it seems like the error you encountered is not related to PlotlyJS but arises since “plotly-artifacts” cannot be obtained from julia’s Pkg server. This issue should be fixed on 1.6 though: "The remote server returned an error: (404) Not Found."

For what it’s worth, this is still a problem on 1.6 for me with PlotlyJS v0.14.1. (but it indeed works without a hitch with the fork linked above)

@jonas-kr Thank you for your fork, it works great on my Windows 10 system running Julia 1.6.1. I couldn’t get the normal version of PlotlyJS to work correctly with errors when ]test PlotlyJS.
