pip install --use-wheel breaks with IndexError

[vmalloc]

I tried the following sequence:

$ pip wheel --wheel-dir=~/wheels sphinx
$ ...
$ pip install --use-wheel --wheel-dir=~/wheels --no-index --find-links=~/wheels sphinx
Traceback (most recent call last):

Running distribute 0.6.24, wheel 1.0.0a1

You need distribute >= 0.6.28. Earlier versions won't find the .dist-info directory that contains wheel's metadata. I recommend upgrading to the newest version of distribute.

we'll soon have a clear error message to explain this requirement

Ok, seems to work for me. Thanks!

BTW - any idea when pip 1.4 RC is planned?

3-6 months most likely

I'm having the exact same issue with distribute 0.6.45 installing celery-with-redis==3.0

[dholth]

celery-with-redis is having a different issue. It looks like pip might be discarding the .dist-info directory, only unpacking its contents, because there are no files at the top level.
