问题
I recently began using julia, and I would like to use in with IPython Notebook/Jupyter.
So, I installed julia using MacPorts, i.e. sudo port install julia. Following the installation instructions here: https://github.com/JuliaLang/IJulia.jl
After the prompt, I used "Pkg.add("IJulia") to install IJulia.
However, I cannot use Julia with IPython notebook. After opening the notebook with
ipython notebook --profile=julia
the kernel for the julia notebook dies instantly and cannot be restarted.
The error on the Terminal shows:
[I 19:03:19.410 NotebookApp] KernelRestarter: restarting kernel (1/5)
WARNING:root:kernel dc00ae3a-8fa6-4d01-a802-f7845a16a9ba restarted

while loading /Users/NAME/.julia/v0.3/IJulia/src/kernel.jl, in expression starting on line 6
I suspect I have installed IJulia incorrectly? How can I solve this?
(The version of julia is julia version 0.3.11. The version of python is Python 2.7.10. The version of ipython is 4.0.0.)
回答1:
The current stable version of Julia is v0.4.0. You should download it directly from the Julia homepage (.dmg):
http://julialang.org/downloads/
Having done that, run it and do Pkg.add("IJulia") again.
Then from within Julia do
using IJulia
notebook()
Note that the Jupyter Notebook (the new name for what used to be the IPython Notebook) is run as
jupyter notebook
The --profile julia is no longer necessary and should be removed.
Furthermore, this (jupyter notebook) will only work if you had a previous installation of Jupyter, which seems to be the case. In this case, I suggest you upgrade it with conda, if you installed Anaconda, or with pip.)
