We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Installation of sunpy via pip with all dependencies fails
python3.6, pip9.03

    pip install sunpy[all]
    ...
    Collecting dateutil; extra == "all" (from sunpy[all])
    Could not find a version that satisfies the requirement dateutil; extra == "all" (from sunpy[all]) (from versions: )
    No matching distribution found for dateutil; extra == "all" (from sunpy[all])

Looks like all other instances of `dateutil` have been updated to `python-dateutil` except in setup.py [here](https://github.com/sunpy/sunpy/blob/master/setup.py#L111)
