Ok, regarding my previous comment: this seems to have been caused by a particular of my setup. My python virtualenv was in ~/usr/local... and this was being 'corrected' by the setup script to ~/local...
So, moving my virtualenv seems to avoid this problem: worth knowing for anyone who likes to install things under ~/usr. The installation is now failing with a permissions error - it is obviously attempting to install into /usr/local/lib - even though I'm within a virtualenv. I don't understand this, but it's not part of this bug so I'll leave it. Summary: this bug is considered fixed but I think the fix breaks for users who have use ~/usr... in their virtualenv. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/780220 Title: pip install numpy fail in virtualenv To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/python-virtualenv/+bug/780220/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
