SystemError: mktempdir: Permission denied

When I am trying to run the example code

using TikzGraphs
using LightGraphs
g = DiGraph(4)
add_edge!(g, 1, 2)
add_edge!(g, 2, 3)
TikzGraphs.plot(g)

in a Jupyter notebook, I met the following error:

SystemError: mktempdir: Permission denied

Stacktrace:

However, I can execute mktempdir directly in Julia:

julia> mktempdir()
"/var/folders/hx/79tr9k0x27b_z93pl1pyspbw0000gn/T/tmpF5waul"

My system is

System Version: macOS 10.13.6 (17G2307)
Kernel Version: Darwin 17.7.0

My Julia version is 1.0.0, the deps are: TikzGraphs v1.0.0, and LightGraphs v1.1.0. My MacTeX version is 2018.0417.

I think this is fixed now; can you confirm?

Confirm, fixed!
