前两天DE库正式支持Julia1.0，测试也能通过，但是使用时报错，请大家看看。

The issue is JuMP.jl is not updated and upper bounds ForwardDiff.jl to a version which is incompatible with v1.0. ]rm JuMP is the fix.
Notice from JuMP:
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.
(Hopefully this response can be appropriately translated! I am using Google Translate to read!)
