Your error message talks about `AlphaColorValue` and `ColorValue`. Those types only exist in the Color package, so something is loading it.
Here's my suggestion: do a `git diff` in the `Color` directory and figure out why it's dirty. Presumably you don't need the changes you made because Color is deprecated anyway. Stash (`git stash`) or discard (`git checkout whatever_file_I_changed.jl`) the changes, then do `Pkg.update()`. This will give you the latest version of Color. The key change is a warning message: WARNING: Color is deprecated, please use Colors instead. See https://github.com/JuliaGraphics/Colors.jl Any time you see that warning, it means you have some other outdated package that needs to be updated. Repeat the above process until the warning doesn't appear. --Tim On Wednesday, September 16, 2015 12:56:37 AM Serge Santos wrote: > I only initialized Colors (i.e., using Colors) and not Color. > > Pkg.status() says > > - Color 0.4.8 2fd36703 (dirty) > - ColorTypes 0.1.4 > - Colors 0.5.3 > > > Serge > > On Wednesday, 16 September 2015 00:12:13 UTC+1, Serge Santos wrote: > > Hi, > > > > I got an error when using the parameter Theme with Gadfly, so I tried > > using an example from http://gadflyjl.org/themes.html#examples (see > > below). > > > > When I run the example from the website below, I get an error saying > > 'convert' has no method matching > > convert(::Type{Union(Nothing,AlphaColorValue{C<:ColorValue{T},T<:Union(Flo > > atingPoint,FixedPoint)},ColorValue{T})},::RGB{UfixedBase{UInt8,8}}).
