Hi all,
I've been playing around with trying to install Julia and some basic
packages system-wide to run a workshop for our department in a couple of
weeks time. Mostly it's working well, and I'm really excited about seeing
what people think!
I ran into the problem that Pkg.dir("PackageName"), although documented as
returning the path to a package, doesn't necessarily do this in the right
way. In particular, if a user has set up their own .julia directory, doing
Pkg.dir("ASharedPackage") returns ~/.julia/v0.x/ASharedPackage even if that
folder doesn't exist.
That is, if JULIA_PKGDIR is not the same as the directory the package is
*actually* in, Pkg.dir("Package") won't give the right location.
I hit this problem trying to get IJulia installed for everyone to use,
becase one of its dependencies Nettle uses Pkg.dir("Nettle") to find itself
when loaded, and so if installed system-wide (in <julia>/local/share) it
won't work.
So, is there a more reliable way to get the path to a package?
[Pkg.dir might need to be smarter instead, but that's more a development
question. I commented on that here
<https://github.com/JuliaLang/julia/issues/8679>]
Cheers,
Scott
