How to use dateutil.relativedelta in Python 3.x?

Question

Hello I am trying to use relativedelta from the dateutil module.

I want to do what is mentioned here, add some months to a given datetime object.

But I'm trying to use Python 3 for this and I am getting the following error:

Traceback (most recent call last):
  File "bin/controller.py", line 2, in <module>
    from dateutil.relativedelta import relativedelta
ImportError: No module named 'dateutil'

I then read that dateutil is now part of Python 3 but how do I import it? import dateutil does not seem to work:

Traceback (most recent call last):
  File "bin/controller.py", line 3, in <module>
    import dateutil
ImportError: No module named 'dateutil'

I am using a virtualenv so I would like to install it with pip.

It seems you have to pip-install it like this and it works :

pip install python-dateutil

Why is it `python-dateutil` and not `dateutil` ? – aairey Aug 07 '16 at 21:07

Because it's the name of the package. It works like this, isn't it ? – acknowledge Aug 08 '16 at 08:35
Yeah, it does but I tried `pip install dateutil` before asking here. Had I known it was `python-dateutil`, my question wouldn't have been necessary :). – aairey Aug 08 '16 at 11:31

You need to install it first using pip3 install python-dateutil. It's not included by default with Python 3, I don't know where you read that.

I added a pip3 and not just plain old pip because that will install it specifically for Python 3.

If you have both python2.X and python3.X installed than you can use sudo python3 -m pip install python-dateutil
