JuMP for 15.083

Follow the steps below to install Julia, JuMP, Gurobi, and IJulia for use in 15.083. If you encounter installation problems, contact huchette@mit.edu or mlubin@mit.edu.

Install Julia

Mac OS X

1. We will use the v0.3.5 binaries provided on the Julia download page. If you are running OS-X Lion, Mountain Lion, or Mavericks, choose the 10.7+64-bit version. Snow Leopard users, the 10.6 64-bit version is for you.
2. Once downloaded, open the .dmg disk image in Finder and then drag Julia-0.3.5.app to your Applications folder.
3. Open the Terminal.app add the Julia executable to your path:

• Run echo PATH=\$PATH:\"/Applications/Julia-0.3.5.app/Contents/Resources/julia/bin\" >> ~/.bash_profile.
