I just upgraded to the latest Plots.jl, and I'm now getting the following error:

I got the same error after updating the dependencies of one of my packages.
For some reason, Pkg.update downgraded Plots.jl to 1.4.3, causing this bug. My fix was to set Plots.jl to the right version manually:

I have no idea why Pkg behaves this way here. This is especially surprising since setting Plots to version 1.9.1 did not force downgrading any other package on my project.

[lincolnq]

Hmm, this is happening for me as well on 1.9.1. I did not have any version of Plots previously installed. ]add [email protected] does not solve the problem on my machine.

[ma010]

somehow installing LsqFit resolved the issue for me.

[pluser]

I solved the problem as update ColorSchemes package manually.

]add [email protected]

Dependency might be broken?

[cultpenguin]

I downgraded StaticArrays, which solved the issue for me.
Seems to be related to #3173

[BeastyBlacksmith]

Should be fixed by JuliaPlots/PlotUtils.jl#104

[Riik]

Updating ColorSchemes fixed it for me too, thanks @pluser

I tried every solution here to no avail. In the end I updated Plots ie Pkg.update("Plots") and it worked.
