I used `sudo pip install ipython jupyter` to install IPython and Jupyter today (May 30, 2016). The output of `pip list`:\r\n```\r\nappnope (0.1.0)\r\nbackports.shutil-get-terminal-size (1.0.0)\r\ncycler (0.10.0)\r\ndecorator (4.0.9)\r\nentrypoints (0.2.2)\r\ngitdb (0.6.4)\r\nGitPython (2.0.5)\r\ngnureadline (6.3.3)\r\nipykernel (4.3.1)\r\nipython (4.2.0)\r\nipython-genutils (0.1.0)\r\nipywidgets (5.1.5)\r\nJinja2 (2.8)\r\njsonschema (2.5.1)\r\njupyter (1.0.0)\r\njupyter-client (4.2.2)\r\njupyter-console (4.1.1)\r\njupyter-core (4.1.0)\r\nMarkupSafe (0.23)\r\nmatplotlib (1.5.1)\r\nmistune (0.7.2)\r\nnbconvert (4.2.0)\r\nnbformat (4.0.1)\r\nnotebook (4.2.0)\r\nnumpy (1.11.0)\r\npandas (0.18.1)\r\npexpect (4.1.0)\r\npickleshare (0.7.2)\r\npip (8.1.2)\r\nptyprocess (0.5.1)\r\nPygments (2.1.3)\r\npyparsing (2.1.4)\r\npython-dateutil (2.5.3)\r\npytz (2016.4)\r\npyzmq (15.2.0)\r\nqtconsole (4.2.1)\r\nreadline (6.2.4.1)\r\nsetuptools (21.2.1)\r\nsimplegeneric (0.8.1)\r\nsix (1.10.0)\r\nsmmap (0.9.0)\r\nterminado (0.6)\r\ntornado (4.3)\r\ntraitlets (4.2.1)\r\nwidgetsnbextension (1.2.3)\r\n```\r\n\r\nWhen I try to run IPython notebook, through the console, or via Sublime Text's SublimeREPL, I get the error listed above. I turned on verbose logging in my `ipython_config.py` and produced the report [in this gist](https://gist.github.com/MattDMo/56c5e4f9cc00402a4e03e5044527517d) (I didn't want this bug report to be huge, but I can add it here if you want).\r\n\r\nI honestly don't know what's going on. I haven't used this computer since last September-ish (I got a new one), but as I recall IPython was working just fine. I do have several other versions of Python installed via MacPorts, so I suppose that *could* potentially be an issue if they're not completely separated somehow. I haven't tried running in a virtualenv (I can if you want), but since this is a fresh install of 3.5.1 I'm not sure what good it would do. The (non-commented-out) contents of my `ipython_config.py` are as follows:\r\n\r\n```py\r\nc = get_config()\r\nc.InteractiveShellApp.exec_lines = [\"import numpy as np\",\r\n                                    \"import pandas as pd\",\r\n                                    \"from pandas import Series, DataFrame\",\r\n                                    \"import matplotlib as mpl\",\r\n                                    \"from pprint import pprint as pp\",\r\n                                    \"def fixquote(): print('\\\"'*3)\"]\r\nc.InteractiveShellApp.gui = 'osx'\r\nc.InteractiveShellApp.pylab = 'osx'\r\nc.InteractiveShellApp.pylab_import_all = False\r\nc.TerminalIPythonApp.gui = 'osx'\r\nc.TerminalIPythonApp.pylab = 'osx'\r\nc.TerminalIPythonApp.verbose_crash = True\r\nc.TerminalInteractiveShell.colors = 'NoColor'\r\nc.TerminalInteractiveShell.autoindent = True\r\nc.TerminalInteractiveShell.editor = 'subl -w'\r\nc.TerminalInteractiveShell.confirm_exit = False\r\nc.PromptManager.color_scheme = 'NoColor'\r\nc.PlainTextFormatter.pprint = False\r\nc.IPCompleter.omit__names = 0\r\nc.IPCompleter.limit_to__all__ = False\r\n```\r\n\r\nIf you have any suggestions, I'm all ears.
