PYZMQ missing when running Ipython notebook

Q:

I can run IPython, but if I try to initiate a notebook I get the following error:

~Ipython Notebook Traceback (most recent call Last): File"/usr/local/bin/ipython", line8,inch<module>Load_entry_point ('ipython==2.1.0','console_scripts','Ipython') () File"/library/python/2.7/site-packages/ipython-2.1.0-py2.7.egg/ipython/__init__.py", line -,inchStart_ipython return launch_new_instance (argv=ARGV, * *Kwargs) File"/library/python/2.7/site-packages/ipython-2.1.0-py2.7.egg/ipython/config/application.py", line563,inchlaunch_instance app.initialize (argv) File"<string>", line2,inchInitialize File"/library/python/2.7/site-packages/ipython-2.1.0-py2.7.egg/ipython/config/application.py", line the,inchCatch_config_error return method (app,*args, * *Kwargs) File"/library/python/2.7/site-packages/ipython-2.1.0-py2.7.egg/ipython/terminal/ipapp.py", line321,inchInitialize Super (Terminalipythonapp, self).

But as far as I can see, I already has the PYZMQ package installed.

Install PYZMQ              in/library/python/2.7/site-packages/pyzmq-14.3. 1-py2. 7-macosx-10.6-intel.eggcleaning up ...

A:

Arg. The ipython install is a little idiosyncratic. Here's what I had to does to resolve this:

Install Ipython[all]

The issue is that notebooks has their own set of dependencies, which aren ' t installed with pip install ipython . However, had installed Ipython, Pip doesn ' t see the need to add anything if you then try the [all] form.
