My suggestion is that you start using virtualenv.

Assuming you have 3.4 installed, then you should also have pyvenv. As for pip and 3.4, it should already be installed.

Using for example version 3.4 create your own virtual environment and activate it:

$ mkdir ~/venv
$ pyvenv-3.4 ~/venv/py34
$ source ~/venv/py34/bin/activate
$ deactive                     # does what is says...
$ source ~/venv/py34/bin/activate
$ pip install ...  # whatever package you need

With version 2.7 first install virtualenv and then create your own virtual environment and activate it. Make sure that setuptools and pip are updated:

$ virtualenv-2.7 ~/venv/venv27
$ . ~/venv/venv27/bin/activate
$ pip install -U setuptools
$ pip install -U pip
$ pip install ...  # whatever package you need
