.dist-info directory not found

[ColmMcBarron]

This seems to have been introduced when upgrading from 1.7.0 to 1.8.0.

Installing via pip is giving the following error:

AssertionError: webcolors .dist-info direction not found

I've locked the version on my end to 1.7.0, so it works.

Here's details about my environment if that helps:

pip: 9.0.1
python: 3.5.1

It can be reproduced on docker image ubuntu:16.04 with python 3.

Hmmm.

Most reports of this seem to be from toolchains expecting a wheel and getting a source package. I've just bumped versions and pushed 1.8.1 onto PyPI in both source and wheel forms (previously there was only source). Try that and see if it works?

Also, most of the other instances I can find of this issue in other projects indicate the install succeeds despite the error message.

Also also: I'm unable to reproduce using pip 9.0.1 on Python 3.5. But I'll keep poking at it.

1.8.1 fixes is on ubuntu:16.04, thanks!

Closing this since it now seems to be resolved.
