pyzmq missing when running ipython notebook

Q:

I can run iPython, but when I try to initiate a notebook I get the following error:

~  ipython notebook                   Traceback (most recent call last):  File "/usr/local/bin/ipython", line 8, in <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 120, in start_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", line 563, in launch_instance    app.initialize(argv)  File "<string>", line 2, in initialize  File "/Library/Python/2.7/site-packages/ipython-2.1.0-py2.7.egg/IPython/config/application.py", line 92, in catch_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", line 321, in initialize    super(TerminalIPythonApp, self).initialize(argv)  File "<string>", line 2, in initialize  File "/Library/Python/2.7/site-packages/ipython-2.1.0-py2.7.egg/IPython/config/application.py", line 92, in catch_config_error    return method(app, *args, **kwargs)  File "/Library/Python/2.7/site-packages/ipython-2.1.0-py2.7.egg/IPython/core/application.py", line 381, in initialize    self.parse_command_line(argv)  File "/Library/Python/2.7/site-packages/ipython-2.1.0-py2.7.egg/IPython/terminal/ipapp.py", line 316, in parse_command_line    return super(TerminalIPythonApp, self).parse_command_line(argv)  File "<string>", line 2, in parse_command_line  File "/Library/Python/2.7/site-packages/ipython-2.1.0-py2.7.egg/IPython/config/application.py", line 92, in catch_config_error    return method(app, *args, **kwargs)  File "/Library/Python/2.7/site-packages/ipython-2.1.0-py2.7.egg/IPython/config/application.py", line 475, in parse_command_line    return self.initialize_subcommand(subc, subargv)  File "<string>", line 2, in initialize_subcommand  File "/Library/Python/2.7/site-packages/ipython-2.1.0-py2.7.egg/IPython/config/application.py", line 92, in catch_config_error    return method(app, *args, **kwargs)  File "/Library/Python/2.7/site-packages/ipython-2.1.0-py2.7.egg/IPython/config/application.py", line 406, in initialize_subcommand    subapp = import_item(subapp)  File "/Library/Python/2.7/site-packages/ipython-2.1.0-py2.7.egg/IPython/utils/importstring.py", line 42, in import_item    module = __import__(package, fromlist=[obj])  File "/Library/Python/2.7/site-packages/ipython-2.1.0-py2.7.egg/IPython/html/notebookapp.py", line 39, in <module>    check_for_zmq(2.1.11, IPython.html)  File "/Library/Python/2.7/site-packages/ipython-2.1.0-py2.7.egg/IPython/utils/zmqrelated.py", line 37, in check_for_zmq    raise ImportError("%s requires pyzmq >= %s"%(required_by, minimum_version))ImportError: IPython.html requires pyzmq >= 2.1.11

But as far as I can see, I already have the pyzmq package installed.

~ pip install pyzmq            Requirement already satisfied (use --upgrade to upgrade): 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 do to resolve this:

$ pip uninstall ipython$ pip install ipython[all]

The issue is that notebooks have their own set of dependencies, which aren‘t installed with pip install ipython. However, having installed ipython, pip doesn‘t see the need to add anything if you then try the [all] form.
