Hypothesis: "setuptools is too old"

[rwst]

virtualenv is 15.2.0 (newest)

(python3.6.3)ralf@ark:~/hypothesis/hypothesis-python> python setup.py install

When you create virtual environment, always do inside of it:

pip install --upgrade pip setuptools

to avoid any issues like this. Because virtualenv & co ships bundled versions on those which are obliviously out of dated.

Also, for Python 3.4+ use builtin venv module instead of virtualenv - it's more modern:

python3.6 -m venv <path-to-virtual-env>
