python - Virtualenv is attempting to install in system directory -

i ran problem earlier, trying install gevent in virtualenv. tried few different things, including few export commands, installing xcode command line tools, installing gcc compiler... none of worked.

in process, managed screw virtualenv install. have removed virtualenv directory , attempting recreate it, no luck. i've uninstalled , reinstalled virtualenv (using pip) , still getting following error after running following command.

command:

virtualenv env 

i'd know why looking in /library installation directory. there setting somewhere fix that?

update v2: removed virtual burrito

update v3: found 1 of things did try install gevent. cause problem?

sudo port install libevent cflags="-i /opt/local/include -l /opt/local/lib" pip install gevent 

this line looks suspicious:

using existing setuptools egg: /users/aharwood/.venvburrito/lib/python/virtualenv-1.9.1-py2.7.egg/virtualenv_support/setuptools-0.6c11-py2.7.egg 

are actively using virtualenv-burrito? i'm not sure does, looking @ install file changes shell's startup commands, may causing problems.

i try , move out of way, open new terminal window, , see if running virtualenv works again:

mv ~/.venvburrito ~/.venvburrito.disabled 

if solves problem, remove more permanently:

rm -fr ~/.venvburrito.disabled 

it installs code in 1 of these files (depending on shell):

~/.bash_profile ~/.zprofile ~/.profile 

you remove code, looks won't cause problems if leave in.
