Hello!  
Im new in Julia/JuMP and im trying to make it work with the cplex i have installed in my mac osx  
In [https://jump.readthedocs.io/en/latest/installation.html](https://jump.readthedocs.io/en/latest/installation.html) It says “Special installation steps are required on OS X”

I was wondering where can i find these steps??

I could only find something in this book:  
[http://www.chkwon.net/julia/book/juliabook-preview.pdf](http://www.chkwon.net/julia/book/juliabook-preview.pdf)  
After managed to make the command Pkg.add(“CPLEX”) work, but then the using CPLEX is giving me this error;

I run out of ideas how to search for this in google, so any guidance is highly appreciated.

Thanks,
