Thanks for the report! What's the result of the following on your system:

julia> homedir()
"/Users/stefan"

julia> joinpath(homedir(), ".julia")
"/Users/stefan/.julia"

[tshort]

julia> homedir()
"C:\\Users\\tshort"

julia> joinpath(homedir(), ".julia")
"C:\\Users\\tshort\\.julia"

Also, I see a copy/paste error in the directory location above. There's a bracket missing. I'll fix that. Actually, multiple errors in username (I'm trying to mask the real name).

[tshort]

I just repeated this on another Windows machine. Same error. On Linux, it works fine.

[StefanKarpinski]

Does C:\Users\tshort\.julia\upstream exist? If not, does mkpath("C:\\Users\\tshort\\.julia\\upstream") create it?

[tshort]

That directory didn't exist. The mkpath statement did create it. Once manually created, the add JSON command now works.

[StefanKarpinski]

Ok, I pushed a potential fix – let me know if it works. You'll have to delete .julia/{upstream,packages} in order to test out if it gets created automatically now. Seems like libgit2 may have a different behavior on Windows in terms of creating parent directories.

[tshort]

That fixed it. I zapped the relevant folders under .julia before retrying it.
