Virtualenv enables you to make different environment with version python or combination of package. virtualenv
$ sudo pip install virtualenv virtualenvwrapper
Setting for virtualenvrapper
$ vim ~/.bashrc
~/.bashrc
if [ -f /usr/local/bin/virtualenvwrapper.sh ]; then
export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh
