I am trying to install Ipopt and Gurobi(810) on JuliaPro 1.0.2, but I failed to use them.

For Ipopt, I got

> ERROR: The following package names could not be resolved:
> 
> - ipopt (not found in project or manifest)  
> Please specify by known `name=uuid`.

For Gurobi, I got

> Error: Error building `Gurobi`:  
> ERROR: LoadError: Unable to locate Gurobi installation. Note that this must be downloaded separately from [gurobi.com](http://gurobi.com)

I have been using JuliaPro 0.6.4 on the same laptop, and both can be installed by one line “Pkg.add()”, and they work fine. Any idea why?

Thanks.
