        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;

        if (!-f $request_filename) {

        virtualenv --no-site-packages $PYENV_HOME
fi
. $PYENV_HOME/bin/activate
pip install --quiet -r requirements.txt --download-cache=/tmp/$JOB_NAME
