Option to import global packages into virtual environment I create?
You can pip download the Python packages you want to install offline and then install the .whl files in your virtualenv. Here is an example with Django and Requests:

Create a directory to store local Python packages:
mkdir local_python
Change directory: cd local_python
Download Python packages to be available offline:
pip download django requests
Install local package .whl files after you activate your virtualenv:
pip install Django-1.11.1-py2.py3-none-any.whl requests-2.16.5-py2.py3-none-any.whl
I am new to using python, so bear with me if I make any assumptions.. So I have virtualenv and pip installed in my ubuntu machine. Every time I create a virtual environment I have to remotely download and install python modules(using pip install) such as django already installed in the main python package. 
The problem is that I am not always connected to the internet. Is there a way I can load modules existing in the main Python to every virtual environment I create? Thanks!
