I try to see an image from vscode, but it doesn’t work, from REPL everything well, but Code doesn’t work:
using Plots, FileIO, ImageView
img = load(“/Users/jar/src/julia/lena_color_512.tif”)
plot(img)

The error is this:

I check Gtk and it’s OK:

How I can load “libgtk-3”?

Can you check if libgtk-3 is present in WinRPM?(somehere in .julia\packages\WinRPM\Y9QdZ\deps\usr\x86_64-w64-mingw32\sys-root\mingw\bin) .
I also had a lot of problems using ImageView/Plots with Cairo and Gtk on Windows and tried a lot of workarounds. Last time I tried to install it just worked, so this makes me think that the connection to the servers is quite fragile and you have to keep trying.
The bad part is that if it fails to download the first time you try, next time you type “using Gtk/Imageview”, it will not complain until you actually try to plot something.
Before trying again I usually delete Gtk and the contents of WinRPM from the path above. Then add Gtk again and wait for it(it takes a while to build)

Here is my complicated workaround which was successful for a few people(as a last resort):

You can also try to rebuild Gtk with :

]build Gtk

Guys.
I uninstall Gtk and not, don’t work…
build Gtk but don’t work.
This I solved by installing an extension in vscode

Thanks to all.
