ImportError: No module named dateutil.parser

You can find the dateutil package at https://pypi.python.org/pypi/python-dateutil. Extract it to somewhere and run the command:

python setup.py install

It worked for me!

For Python 3:

pip3 install python-dateutil

On Ubuntu you may need to install the package manager pip first:

sudo apt-get install python-pip

Then install the python-dateutil package with:

sudo pip install python-dateutil

I have same issues on my MacOS and it's work for me to try

pip3 install python-dateutil

on Ubuntu

sudo apt-get install python-dateutil
