I'm attempting to add JuMP, but it's returning an error.

└─restricted by julia compatibility requirements to versions: uninstalled — no versions left
It looks like Julia is restricting to versions: uninstalled — no versions left. Any idea what might be going wrong here?
JuMP isn't ready for Julia v1.0 (or v0.7) yet.
Citing from there github page:
The latest release of JuMP (based on MathProgBase) is not compatible with Julia 0.7 or 1.0. We encourage users to continue to use Julia 0.6 for a stable environment. The development version of JuMP (based on MOI) supports both Julia 0.6 and Julia 0.7 but is alpha-quality with breaking changes in still progress. See the Discourse post for more information on Julia 0.7/1.0 support.
