python - Pip doesn't install packages to activated virtualenv, ignores requirements.txt -

i attempting setup development environment on new dev machine @ home. have installed ubuntu , attempting clone remote repo our web-server , install dependencies can begin work.

so far have manually installed virtualenv , virtualenvwrapper pypi , edited bash.rc appropriately source virtualenvs when start terminal. cloned repo ~/projects/project-name/websitename.com. used virtualenvwrapper mkvirtualenv env-name ~/projects/project-name/websitename.com. reflects file-structure/setup of web-server cloning from. far good.

i logged dev server , activate virtualenv there , use pip freeze -l > req.txt render dependencies list , scp local machine. activate virtualenv on local machine, navigate ~/projects/project-name/websitename.com , execute pip install -r path-to-req.txt , runs through of dependencies if nothing wrong. however, when attempt manage.py syncdb error not finding core django packages. hell? figure somehow django failed install, run pip install django==1.5.1 , completes successfully. got setup site again , error no module named django_extensions. okay, hell it, installed of these packages pip?!

so pip freeze -l > test.txt , cat test.txt, list? django==1.5.1, 1 package manually installed. why isn't pip installing dependencies specified list virtualenv? messing here?

-edit-------------

which pip gives me path pip in virtualenv

i have 1 virtualenv , activated

my usual workflow

pip freeze > somefile.txt 

and install with

pip install -r somefile.txt 

so i'm should work fine. unfortunately can't tell besides make sure check that

1. you in virtualenv think in. make sure run

   workon yourvirtualenvname 

   to activate in case matters.

2. make sure check pip within virtualenv.

   which pip 

   gives me

   /path/to/home/.virtualenvs/myvirtenv/bin/pip 

sorry can't give more concrete answer. have semi-regularly , i've never had problem skipping dependencies. best of luck!
