Error creating virtualenv with Python3

Question

I'm working on Linux Mint 17 and I'm trying to create a new virtualenv with Python3 like this:

python3.6 -m venv env

And this is the error that I get:

Error: Command '['/home/ric/myprojs/django-example-channels/env/bin/python3.6', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.

I've googled this error message but haven't managed to find anything too informative.

This is my pip version, in case it make any difference:

pip --version
pip 9.0.1 from /usr/local/lib/python2.7/dist-packages (python 2.7)

I've been using Python2 for some time, but I'm new to Python3. I don't know what I may be missing.

UPDATE 1:

Answering @cezar's question, when I type which python3 this is what I get:

$ which python3
/usr/bin/python3

UPDATE 2:

Answering @Chłop Z Lasu:

$ virtualenv -p python3.6 env
Running virtualenv with interpreter /usr/bin/python3.6
Using base prefix '/usr'

You run python3.6 from your virtual environment. In Linux Mint 17 python3 is installed per default and should be available under /usr/bin/python3. What happens if you do which python3? — cezar

Your question is about the python standard library module venv (docs.python.org/3/library/venv.html). That is not the same as virtualenv (pypi.python.org/pypi/virtualenv). Maybe you should edit the tags to reflect this. — cezar

By the way, pip3 --version is what you should check, notice that output is Python2 — OneCricketeer

The error indicates that virtualenv is trying to make an environment in your python path. therefore, you have to specify your virtualenv destination

virtualenv -p python3.6 /path/to/yourenv
