This bug is due to the shipped version of virtualenv (1.4.9 in ubuntu 11.04). This version does not copy the directory config/ of the python installation in the virtualenv, so sysconfig, introduced in python2.7 is broken.
Here is a workaround: mkdir -p <VIRTUALENV_PATH>/local/lib/python2.7/config/ cp /usr/lib/python2.7/config/Makefile <VIRTUALENV_PATH>/local/lib/python2.7/config/Makefile -- 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 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
