pyzmq dependency not properly advertised

[staticfloat]

I was able to install IJulia just fine, but when I tried to run ipython notebook --profile=julia, I was met with the following error:

ImportError: IPython.html requires pyzmq >= 2.1.11

After a sudo pip install pyzmq, the startup process succeeded.

How did you install IPython notebook? Correctly done it should pull pyzmq/jinja/tornado etc... (and sudo is not alway required)

[staticfloat]

I installed by downloading the source tarball and running python setup.py install. In this case, sudo is required because my pip comes from the distribution python, which is installed to /usr and is owned by root. :/

It does though show optional dependencies

$ python setup.py install

When installing IPython directly via pip as said in the doc it should pull what is needed if you specify that you want the notebook.

Problem is when you just do python setup.py install we can't guess which part of IPython you want to install.

[staticfloat]

I see. Maybe we should advertise pyzmq here then, alongside jinja2 and tornado?

Try uninstalling pyzmq first.

sudo pip uninstall pyzmq


And then install it again:

sudo pip install pyzmq


I had the same error as you and it worked for me.

If your working on a virtualenv try exiting and loading again.

E.g. using virtualenvwrapper

% deactivate
% workon IPython
