dreampie was created in Python 2.7 and it needs Python 2.7 to run it.
You have to install in with pip2 install ... or python2 -m pip installl ...

If you don't have Python 2.7 then you can install it from
deadsnakes unofficial Python repo for Ubuntu (and Mint)

https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa

After that you can use Python 3 inside dreampie

 $ dreampie python3
 $ dreampie python3.7
 $ dreampie python3.8

or even ipython or bpython installed in Python 3

 $ dreampie ipython
 $ dreampie bpython

dreampie was created in Python 2.7 and as I know
It could need too much change to simply convert it to Python 3
ie. it uses gtksourceview2 which doesn't exists in Python 3
and I had problem to install it on Linux Mint 20 based on Ubuntu 20.04

If you will have problem with gtksourceview2 in Python 2.7
then download python-gtksourceview2_2.10.1-3_amd64.deb
from

https://ubuntu.pkgs.org/18.04/ubuntu-universe-amd64/python-gtksourceview2_2.10.1-3_amd64.deb.html

and install it with double click

or uncompress it using function built-in in Nautilus/Caja
or using dpkg -x python-gtksourceview2_2.10.1-3_amd64.deb folder

and copy gtksourceview2.so to folder with Python 2

At Linux Mint it is /usr/lib/python2.7/dist-packages/gtksourceview2.so

It may need also to install libgtksourceview2.0-0 with apt-get
