Can't run `jupyter notebook` after fresh installation

Question

I did:

pip install --upgrade pip
pip install jupyter
jupyter notebook

And I get the following error:

    Traceback (most recent call last):
  File "/usr/local/bin/jupyter-notebook", line 7, in <module>
    from notebook.notebookapp import main
  File "/Library/Python/2.7/site-packages/notebook/notebookapp.py", line 61, in <module>

Thanks.

It seems that some Matplotlib users had similar issue (see there ) and solved it by re-installing dateutil .

sudo pip uninstall python-dateutil
sudo pip install python-dateutil==2.2

You might want to try with a newer version (the latest is 2.6).
