Weird errors installing Julia client and ink

Windows 10 here.
First I tried the package installer in Atom. That failed (incompatible version of uber-juno 0.2??).
Then I got down to the command line and I got:

$ apm install ink
Installing ink to C:\Users\PK\.atom\packages failed

Is this a known issue? How does one deal with it? Even wiping the .atom folder clean does not help.

Wiped Atom cleanly off my computer. Fresh install from the installer: no problem installing uber-juno 0.2.0, all went smoothly. Go figure. The only thing I can think of that was different the second time around was that the first time I did not have Julia installed, the second time it was already installed and in the path. Would that make a difference?

Third time around: no Julia, installation of ink as above, same failure.

Fourth installation: from the installer, with Julia, no problems.
