I’m always scared away by python dependecy management. I’m always pissed off when I’m trying to install a pip package only to conflict with the system managed ones. Now I fainally take the chance to take a look at venv.

§ How does python (pip) manage packages?

AW: they fuck you.

§ How does linux distro manage python packages?

AW: they fuck you.

§ the venv (python 3.3+)

# create
$ python -m venv <name>   # python 3.3
$ virtualenv <name>       # python 3

# activate
$ source envname/bin/activate

# deactive
$ deactivate  # (while in virtenv)
