How to setup a pipenv Python 3.6 project if OS Python version is 3.5? : <p>My Ubuntu 16.04.03 is installed with Python 3.5.2. How do I setup pipenv to use Python 3.6 when my system does not have python 3.6?   </p>

<pre><code>$ pipenv --python 3.6
Warning: Python 3.6 was not found on your system…
You can specify specific versions of Python with:
  $ pipenv --python path/to/python
</code></pre>
