ERROR: key not found: "HOME"

My new ipython notebook seems to work but I get this from my julia kernel. How can I fix this?

Sounds like you have a bug in your .juliarc.jl file? (This is a file in your home directory with user code, i.e. your code, that is loaded when Julia is launched.)

[stevengj]

(What operating system and Julia version are you running?)

[marmalodak]

I'm using Fedora 21. I've created a virtualenv for ipython3 which seems to work well. However, I've just learned that I might have to use the jupyter/jupyterhub packages rather than the ipython packages? I'll try that.

[stevengj]

On a Unix system, the Base.homedir() command assumes that you have a HOME environment variable...is there any reason why this might not be defined in a virtualenv?

[marmalodak]

It is defined and it points to /root. At least, I see a $HOME when I manually activate the venv and look.

[stevengj]

That's weird, because the ERROR: key not found: "HOME" would be the error that would occur if ENV["HOME"] (which is run to find the home directory when loading the juliarc file) failed to find that environment variable.
