Warning: _display is not defined for this backend.[BUG]

[dtxl]

Details

Installed julia 1.10.0 (on macOS Ventura 13.6.3).

Running a code via Visual Studio Code 1.85.1, the Plot by "plotlyjs()" doesn't appear, but the error message

Warning: _display is not defined for this backend.
@plots ~/.julia/packages/Plots/sxUvK/src/output.jl:211

With the Julia version 1.9.4 it worked yesterday.

Backends

I run: test backend and for "test UnicodePlots", "test PythonPlot", "test PGFPlotsX", "test InspectDR", "test Gaston" it gives:

With the same installation of julia 1.10.0, on Win10 when loading PlotlyJS, the error message is

┌ Warning: Kaleido is not available on this system. Julia will be unable to save images of any plots.
└ @ PlotlyJS C:\Users_username_.julia\packages\PlotlyJS\qhYQ5\src\kaleido.jl:65
┌ Warning: ErrorException("Could not start Kaleido process")
└ @ PlotlyJS C:\Users_username_.julia\packages\PlotlyJS\qhYQ5\src\kaleido.jl:66

But kaleido.exe is in C:\Users_username_.julia\artifacts\7914a56da888d6a06d00c87f97e873c60e97acc7\bin

During the execution of Julia code under macOS, the message

┌ Warning: backend 'PlotlyJS' is not installed
└ @ Plots ~/.julia/packages/Plots/sxUvK/src/backends.jl:43

but PlotlyJS is installed and has been loaded.

[BioTurboNick]

Hmm, I tried to reproduce on Windows 11 and it seems that Julia hangs when loading PlotlyJS. When I interrupt I get the "Kaleido is not available" message. But that may be a PlotlyJS.jl issue, not a Plots.jl issue.

Which is reported here: JuliaPlots/PlotlyJS.jl#479

[dtxl]

Yes, that is a PlotlyJS issue. I have reinstalled Julia 1.9.4 and the error message is now under Win10 and macOS
┌ Warning: backend PlotlyJS is not installed.
└ @ Plots C:\Users\username.julia\packages\Plots\sxUvK\src\backends.jl:43
but PlotlyJS works.

[dtxl]

Since JuliaPlots/PlotlyJS.jl#479 has been closed, I'm closing it here too.
