ERROR: `width` has no method matching width(::Canvas) about imageview.jl

What does Pkg.status() say? Does Pkg.update() fix the problem?

[andrewadare]

I had run Pkg.update() just before my example. If I run it again, it says INFO: No packages to install, update or remove.

For good measure, I repeated the example after running Pkg.update() again, and got the same error. FWIW, I also tried the same example on my work machine (ubuntu trusty using v0.3.6 and freshly updated packages). I got the same exact error. So this doesn't appear specific to the configuration on my mac.

I can reproduce this here. It's something that slipped in recently.

Before this morning's Pkg.update(), everything worked with this Pkg.status():

63 required packages:
...
 - Cairo                         0.2.24
 - ImageView                     0.1.10             master
 - Images                        0.4.30             master
 - Tk                            0.2.17
53 additional packages:
...
 - Homebrew                      0.1.13

After Pkg.update(), the broken versions are:

63 required packages:
...
 - Cairo                         0.2.24
 - ImageView                     0.1.11             master
 - Images                        0.4.31+            master
 - Tk                            0.3.0
53 additional packages:
...
 - Homebrew                      0.1.13

Julia after the update is Version 0.3.7-pre+15 (2015-03-02 23:43 UTC)

It got introduced with JuliaGraphics/Tk.jl@7f45f9a. Basically, all graphics packages either have to use Base.Graphics or Graphics; you can't have some of each.
