From c428cd52282dcc967b2a936d80f1eec4cb80d6d5 Mon Sep 17 00:00:00 2001 From: Tim Bird Date: Mon, 24 Feb 2020 18:34:41 -0700 Subject: scripts/sphinx-pre-install: add '-p python3' to virtualenv With Ubuntu 16.04 (and presumably Debian distros of the same age), the instructions for setting up a python virtual environment should do so with the python 3 interpreter. On these older distros, the default python (and virtualenv command) might be python2 based. Some of the packages that sphinx relies on are now only available for python3. If you don't specify the python3 interpreter for the virtualenv, you get errors when doing the pip installs for various packages Fix this by adding '-p python3' to the virtualenv recommendation line.
