24761	Cannot `pip install` the zip of master	Keryn Knight	nobody	"I'm pretty certain I used to be able to do this, though I'm not sure how long ago it was:
{{{
pip install https://github.com/django/django/archive/master.zip
}}}
which is ostensibly the quickest way to get a copy of `master` (currently targetting `1.9.x`) without doing a `git clone`, which takes a bunch of time. It's also the easiest way of setting up continuous integration against `master` (eg: I think one of the ways in which I previously used this was to have travis-ci build using it to check for upcoming failues)

This no longer works, giving the following traceback:
{{{

the `path` at the point of error is: 
{{{
path = u'django-master/tests/staticfiles_tests/apps/test/static/test/\u2297.txt'
}}}
I raised a bug against [https://github.com/pypa/pip/issues/2729 pip itself] assuming that the lack of unicode handling was a problem in pip, but a response suggests that there is no safe fix for their end (because of how zip works?) and that Django ought to create & destroy such test files as part of the test case, rather than statically embedded on a known path, which seems sensible enough, if it's feasible in the test cases which touch such files.
