I've been trying to get IJulia to work on Ubuntu 12.04 with Julia Version
0.3.0-prerelease+2057. I installed ipython 2.0.0 using easy_install:
easy_install ipython[all]
and this allows me to run an ipython notebook from the terminal with:
ipython notebook
This all works fine. I then attempted to install IJulia with
Pkg.add("IJulia")
and this all seemed to work well. When I run
ipython notebook --profile julia
a notebook opens with the Julia logo at the top right. However, when I open
a new notebook, the kernel appears permanently busy (I can write in
markdown script and headers, but I can't execute any Julia code) and I get
the following error message in the terminal:
2014-04-11 18:56:44.881 [NotebookApp] Creating new notebook in /

If instead I run
ipython console --profile julia
I don't even get so far as anything opening at all: I just get the same
error message.
This error and others similar to it have appeared in a number of places,
for example:
https://github.com/JuliaLang/IJulia.jl/issues/61
https://groups.google.com/forum/#!msg/julia-users/MJrSqN1CcDs/SrbQOL2yMTkJ
https://groups.google.com/forum/#!msg/julia-users/MhTP9T-j5FY/PP_Su47p8RoJ
The reason for the error and suggested fixes vary considerably. I've tried
deleting ~/.ipython/profile_julia and running Pkg.fixup("IJulia"). I've
tried removing IJulia and then running Pkg.add("WinRPM") and then
Pkg.add("IJulia"). So far the error message hasn't changed.
Any help would be appreciated :)
