Ubuntu 14.04's Python 3.4 installation has a problem with ensurepip module, as described in this bug. So if you follow the steps mentioned in the official documentation, you would see an error message like this

1➜  Python  python3 -m venv py3.4venv
2Error: Command '['/home/thefourtheye//py34venv/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1

To resolve this problem, first install the venv, without pip, like this\\

1python3 -m venv py3.4venv --without-pip

And then if you install pip, like this, it will still fail

1(py3.4venv) ➜  py3.4venv  python -m ensurepip --upgrade
2/home/thefourtheye/Python/py3.4venv/bin/python: No module named ensurepip
3(py3.4venv) ➜  py3.4venv  python

So, you need to install, pip separately, like mentioned in the pip's official documentation. So, the actual list of steps go like this\\

 1➜  Python  python3 -m venv py3.4venv --without-pip
 2➜  Python  cd py3.4venv
