how to update WinRPM in julia version 0.6.4

[farzanfarahani24]

I'm new to Julia and I want to use COBRA Package. For adding COBRA I use the command :

Pkg.add("COBRA")
But when running, I get these errors:

INFO: Building WinRPM

WARNING: skipping repodata/repomd.xml, not in cache -- call WinRPM.update() to download

until:

After these errors, I have checked the link and I've found out the source is not there, anymore. So then I ran this command as said above:

WinRPM.update()
But it has thrown this error:

ERROR: UndefVarError: WinRPM not defined

I'm using version 0.6.4 (Windows 10).
Any help would be appreciated.

Finally I've found out that the mentioned links are broken and new links were replaced after upgrading Julia; So this problem is resolved in new version of Julia (1.0+)
