If you are running on a Windows machine, there are a few steps to get Julia on Jupyter. Remember, this environment was really developed for Linux.
First, we need to install Julia on your Windows machine. Navigate to the Julia download page (http://julialang.org/downloads/), download the correct version, which is Julia 0.4.5 for Windows (in my case, I used the Windows self-extracting EXE file for 32-bit machines), and run the installation with standard defaults.
