Installs with pip on python 2

[BertRaeymaekers]

Hi,

I pip installed wily on a python2. And pip allowed me to do that. But it shouldn't work given that you use f-strings. I think it is possible to indicate a minimal python version (3.6?) on pipy.
Perhaps this isn't an issue against the code base, but as I can't think of a better place to report it, I'll do it here.

Bert

thanks Bert.

It specifies Python 3.6+ in the metadata, which should raise a warning/error for older versions of Python. https://github.com/tonybaloney/wily/blob/master/pyproject.toml#L31
That metadata tag was only introduced in the 1.2 Metadata API

Curious to know:

• Which version of Pip are you using?
• Which version of wily did it install?

It looks like it is installing WIly 0.2.0 on python 2.7 (pip 18.1)

Looks like I added the metadata after version 0.2.

Have removed early builds from PyPi, verified this now gives the correct message:
