Pkg.jl: Pkg3 not installing packages

[nico202]

Hi, I'm very optimistic about the new package manager. However, I can't get it to install anything. Following the readme:

using Pkg3

]

pkg> add JSON

ERROR: The following package names could not be resolved:

Hmm, I can not reproduce.

Could you try delete .julia/registries and try again?

[nico202]

Yes, this worked. I don't know why it wasn't created (the dir was empty). I had tried deleting the v0.6 folder but nothing changed. Thanks

I'm experiencing the same issue on today's master (built with precompiled Pkg3: export JULIA_PKG3_PRECOMPILE=true; make). After removing the registries folder, this is what happens:

pkg> add JSON
[ Info: Pkg3 is still under development, please file issues at `https://github.com/JuliaLang/Pkg3.jl`.
[ Info: Cloning default registries into /home/pietro/.julia/registries
[ Info:  [+] Uncurated = "https://github.com/JuliaRegistries/Uncurated.git"

Strangely enough there actually is a folder called JSON: ~/.julia/registries/J/JSON

EDIT: I've just seen the message on slack, will wait a few more days until it stabilizes a bit more and then try again.

[KristofferC]

You should only have to wait a few hours until https://github.com/JuliaLang/julia/pull/26152 is merged.

[piever]

Yes, that fixed it : it works beautifully now!

[meteorologytoday]

Same problem here using compiled binary version.
delete ~/.julia/registries solves my problem as KristofferC suggested

[alhirzel]

Deleting %USERPROFILE%\.julia\registries worked on Windows.
