python - Pip install results in error "no such option: -E" -

i cleaned mac after mavericks install (yeah, i'm late party). i'm using homebrew python i've confirmed error stock apple python well. i've got pip 1.5.6 installed system-wide , in virtualenv.

i can pip-sys install system-wide pip installs no problem. when in virtualenv though, next error, which pip.

pip install -u -r requirements/dev.pip usage: pip <command> [options] no such option: -e

seems there wrong pip install within virtualenv. pip not working pip2 install works fine. maybe there's version conflict pip installs thinking it's different python version installed.

to recap

pip install south

fails above error

pip2 install south

works fine.

python django pip virtualenv
