Ipython notebook will not start on command line

问题:

I tried to open ipython in terminal with ipython notebook and it will not open ipython notebook. It gives the following error:

I have upgraded conda jupyter but it still won't work. How can I fix this?

回答1:

This issue due to the newest Mac OSX 10.12.5 upgrade. Please follow these steps to fix it:

1. Generate jupyter config if you don't have it:
   jupyter notebook --generate-config
2. Use vim to open that config file and add Google chrome value in:
   c.NotebookApp.browser = u'chrome' (Make sure to take out the # comment sign)

回答2:

I used the same approach as Kiem Nguyen above, but 'chrome' wouldn't work for me, even after editing my .bash_profile as Hanshenry90 suggested.

To use Safari to view the notebook, open your terminal and enter:

jupyter notebook --generate-config
cd ~.jupyter
nano jupyter_notebook_config.py

ctrl + w "NotebookApp.browser" + enter to skip to that part of the file. Then delete # and change the line to:

c.NotebookApp.browser = u'Safari'

Restart your notebook, with jupyter notebook, and it should open in Safari.

If anyone has any insight on how to make this work for Chrome, that would be much appreciated.

I liked most imarti's solution:

export BROWSER=open

It is low overhead and works with your default browser

EDIT: macOS 10.12.6 has been released, so now the recommended solution is to just update your OS.

回答4:

editing my nano .bash_profile file to contain the lines:

BROWSER=/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome
export BROWSER

Not the best fix, but a potential workaround...

Go to your browser and enter the login token provided. In your case: http://localhost:8888/

After starting a new notebook, I found that my kernel would die and be unable to restart. Updating my ipykernel fixed this:

pip install ipykernel --upgrade

This is an issue possibly due to the recent upgrade of Mac OSX. You can follow the discussion and possible solutions here, here and here.
