在virtualenv-15.1.0目录下：
ubuntu@ubuntu:~/mydocument/virtualenv-15.1.0$ python setup.py build
ubuntu@ubuntu:~/mydocument/virtualenv-15.1.0$ sudo python setup.py install

用 python2.7创建环境myenv2.7
ubuntu@ubuntu:~/mydocument/virtualenv-15.1.0$ virtualenv -p python2.7 myenv2.7

# Activate the my27project sandbox and check the version of the default Python interpreter in it:
source my27project/bin/activate
python --version
# This will show Python 2.7.6
deactivate

# Activate the my33project sandbox and check the version of the default Python interpreter in it:
source my33project/bin/activate
python --version
# This will show Python 3.3.5
deactivate

把Django安装文件放在myenv2.7 目录下：
