zappa not using virtualenv python-dateutil

[rhyspowell]

When trying to update getting the following error. This was previously deployed and updated on another machine.
As can be seen from the output its calling directly from system packages despite the correct versions being available in the virtual environment

`(venv) ➜ fatalshadows git:(master) ✗ zappa update dev [20/479]
(python-dateutil 2.7.3 (/Users/rhyspowell/.pyenv/versions/3.6.2/lib/python3.6/site-packages), Requirement.parse('python-dateutil==2.6.1'), {'zappa'})
Calling update for stage dev..
Oh no! An error occurred! :(

Zappa please update to python-dateutil >= 2.7.3

[davesave]

zappa 0.46.2 has requirement python-dateutil<2.7.0,>=2.6.1, but you'll have python-dateutil 2.7.3 which is incompatible.

[rhyspowell]

Which is fine but it's calling dateutil from my system python, not the virtual env. I don't want to have to keep changing versions everytime I run this project. I believe since the last time tun, zappa has been upgraded, has it fixed this issue?

[prattcmp]

This is still an issue AFAIK.

[LeggoMahEggo]

Getting this issue with zappa 0.48.2

[gonwi]

Still an issue

[MikaylaRobinson]

I added python-dateutil==2.6.1 to my requirements before zappa and it worked for me.

[Number77asa]

pip install python-dateutil==2.6.1
