I’m using Julia-1.3.1 on Windows 64. To install NEOS.jl, I’ve used the followings:  
Julia\>import Pkg  
Julia\>Pkg.add(“NEOS.jl”)

ERROR: The following package names could not be resolved:

- NOES.jl (not found in project, manifest or registry)  
Please specify by known ‘name=uuid’.

Did you actually copy and paste the input and error? Because the input says NEOS but the error message says NOES.

Neos.jl does not work on Julia 1.x or recent versions of jump.

Pull requests to update the code appreciated.

I’ve typed it. IT is NEOS.jl.
