Fabric 2.0: [Errno 2] No such file or directory: 'LICENSE'

Hi,

When installing the recent 2.0 release, the install fail when building wheel:

Thanks for the amazing work !

I also encountered the same problem, did you get it working?

[alorence]

A few minutes after my first message, the package was removed from pypi and re-added later. After that, I was able to install it in a fresh virtualenv.
Unfortunately, I didn't succeed to port my old fabfile to the brand new fabric2 API. So I stopped to work on it at the moment, and will re-try as soon as I have more time

It looks there is indeed a packaging problem.
On PyPI the Python 2 version is distributed as a wheel package while installing from Python 3 downloads a tar.gz that is missing the LICENSE file referred in setup.cfg.

pip as default tries to build a wheel from the downloaded tar.gz and fails for the missing file.
Right now the way to obtain a clean install is to pip install --no-cache-dir to force pip to install from setup.py bypassing the wheel build step.

I hope that Jeff will distribute a .whl for Python 3.

That's got to be some weird issue with my packaging scripts; the intent was to distribute:

• source tar.gz
• single Python 2+3 compatible wheel

But it sounds like something's gone sideways in a fashion that did not cause errors on my end. I'll take a look ASAP. Thanks all for the reports!

Yuuuup I copied my setup.cfg from the ONE project of mine that cannot build universal wheels (it must distribute dual 2 vs 3 wheels). So I was missing [wheel] universal = 1. Ugh. Fixing now.

[bitprophet]

Did a stealthy force push due to a minor mishap, but 2.0.1 is now up on PyPI and appears to have the proper universal wheel now.
