Virtualenv搭建python3环境并安装djangoproject

django.py

sudo pip install virtualenv
sudo apt-get install python3

virtualenv --no-site-packages --python=python3.4 test_env
如果出现The executable python does not exist 错误，那么可以这样使用
virtualenv --no-site-packages --python=3.4 test_env

source test_env/bin/activate
pip install django

virtualenv  pip install django
import django

deactivate
