KeyError: key "git-tree-sha1" not found (Windows)

[amellnik]

I'm on 00ac33a3ef (12 March), and I've seen this over the past month or so.

Init works OK:

pkg> init
[ Info: Initialized environment by creating C:\Users\amellnik\AppData\Local\Julia-0.7.0-DEV\Project.toml

But any add fails immediately:

pkg> add IJulia
[ Info: Resolving package versions
ERROR: KeyError: key "git-tree-sha1" not found

Solved by Sebastian Pfitzner on Slack -- I needed to delete all non-v0.6 directories in .julia.

Can you try do an pkg> up first.

[KristofferC]

Oh. I think the problem here was an old registry.
