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.egg Cleaning 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.
