I tried to install JuMP 0.18.4 in Julia version 1.0.1, and it succeeded. When I tested the package, however, it told me to rebuild the SpecialFunctions. But then it failed to build this because of a LoadError: Unable to open libLLVM! as follows.
When I was firstly installing JuMP, it also reported this issue and failed, but later it succeeded after I tried and failed rebuilding the SpecialFunctions, which is weird.
Can somebody help me out with this? Thank you!
