I’m using Julia 1.2.0. Just now, I tried to install JuMP and GLPK (using
Pkg.add), and then tried to use them with
using .... The attempt to precompile led to a slew of errors, and a segmentation fault (this is in Linux). When I installed them on a work computer, running Windows 10 and an older version of Julia, both installed and ran fine.
In fact, something even worse has happened, as I’ve just discovered: I seem to have broken something, as Julia just crashed and now can’t start (in a terminal); attempts lead to a segfault.
What has happened? Why is Julia crashing on starting, and why couldn’t I install either JuMP or GLPK? Thanks!
