Error loading a package



Today I’ve installed the package

The installation didn’t generate any error message.

But When I try to load it I get this error:

Checking if there is an existing issue on github and opening one if there isn’t may be the quickest way to a fix, unless the author is reading this forum.


The warnings are there because of a few key syntax changes that were made to Julia:

immutable -> struct
type -> mutable struct
abstract -> abstract type
typealias -> const ALIAS = ORIG

(To name a few. -see for more info).

The package was written for Julia v0.5 (or earlier) - and the previous syntax is will only be “compatible” (with warnings) for a few versions (actually, I think it will no longer be supported in v0.7).

Like @Tamas_Papp says: you might want to raise the issue on the EvolvingGraphs.jl GitHub page…

…you could also try using this package from a Julia v0.5 installation if you don’t want to wait for the fix.


OK, I’ve raisen an issue on the EvolvingGraphs.jl GitHub page.
