Just pulled devstack from github and tried ./ but installation process halts with the following log:

env http_proxy= https_proxy= no_proxy= PIP_FIND_LINKS=file:///opt/stack/.wheelhouse /opt/stack/requirements/.venv/bin/pip install -c /opt/stack/requirements/upper-constraints.txt -U pbr

2015-09-18 20:22:35.600 | pip install [options] <requirement specifier=""> [package-index-options] ... 2015-09-18 20:22:35.600 | pip install [options] -r <requirements file=""> [package-index-options] ... 2015-09-18 20:22:35.600 | pip install [options] [-e] <vcs project="" url=""> ... 2015-09-18 20:22:35.600 | pip install [options] [-e] <local project="" path=""> ... 2015-09-18 20:22:35.600 | pip install [options] <archive url="" path=""> ...

2015-09-18 20:22:35.601 | no such option: -c

shouldn't pip have a -c option?

running on ubuntu 14.04

Such error may appear if you haven't removed all artifacts of old Devstack installation. Clean setup of Devstack should resolve such problem.

It worked for me.

I had the same problem the virtual version was old, After upgrading to 15.0.1 using 'pip install -U virtualenv' I didn't have the problem

Have you tried ./ before relaunching devstack? Sometimes, as vponomaryov mentioned, we have old artifacts left. Though I really doubt that "pip -c" would be a problem attributed to an untidy devstack "unstacking", but try to execute "clean" before realunching devstack
