Ok, I just tried this and got this error.

jfb at jims-mint18 ~ $ python3.6 -m venv /home/jfb/EVs/env365 && 
./venv/bin/pip help
The virtual environment was not created successfully because ensurepip 
is not
available.  On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

     apt-get install python3-venv

You may need to use sudo with that command.  After installing the 
python3-venv
package, recreate your virtual environment.

Failing command: ['/home/jfb/EVs/env365/bin/python3.6', '-Im', 
'ensurepip', '--upgrade', '--default-pip']

Couple of things troubling about this message. I just checked and 
python3-venv is installed, in fact I used it to install the python3.6 
environment I'm having problems with. I did a search and ensurepip is on 
my system at //usr/lib/python3.6/ensurepip.
