JuMPeR installation problem with JuliaPro 1.0.5-2

This is the error message that appears to me when I try to install JuMPer

I can’t find the version that is compatible with JuMPeR

This bit says you have JuMP installed, but it is fixed to version 0.21.3.

 └─restricted by compatibility requirements with JuMPeR [707a9f91] to versions: 0.18.5-0.18.6 — no versions left

but this bit says that JuMPeR wants JuMP version 0.18.6.

Since we can’t have 0.18.6 and 0.21.3 installed at the same time, you can’t install JuMPeR.

You will need to install JuMP 0.18.6 if you want to use JuMPeR.
