Hi! The community here will be happy to try to help you, but I think it will be difficult for people to help with so little information. Can you paste what are you doing and the full error that you get when trying to add this package?
[Also, this post may be of help](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you)

It appears MultiJuMP is not compatible with the latest version of JuMP. You should open an issue in MultiJuMP.
For reference, the error is:
