Virtualenv is usefull to create isolated environments for Python projects.
Install pip
sudo apt-get install python-pip
Install virtualenv
sudo pip install virtualenv
Create a dir to store your virtualenvs
mkdir ~/.virtualenvs
At this point you are all set to use virtualenv with the standard commands. However, I prefer to use the extra commands included in virtualenvwrapper. Lets set that up.
Install virtualenvwrapper
sudo pip install virtualenvwrapper
Set WORKON_HOME to your virtualenv dir
export WORKON_HOME=~/.virtualenvs
Add virtualenvwrapper.sh to .bashrc
Execute this script:
. /usr/local/bin/virtualenvwrapper.sh
Exit and re-open your shell, or reload .bashrc with the command . .bashrc
and you’re ready to go.
Create a new virtualenv
mkvirtualenv myawesomeproject
to exit your new virtualenv, use deactivate
.
Switch between enviornments with workon
To load or switch between virtualenvs, use the workon
command:
workon myawesomeproject
You can read more about virtualenv here and virtualenvwrapper here. You might also want to look at this very similar (and probably better) python guide post.
