Same issue, here is my solution.
If you run pip install dashing, you can import ColorRangeVGauge, but you will fail to run demo.py because open_terminal() is missing, but if you implement open_terminal() manually (same with the implementation in __init__.py), it arises TypeError: Tile.display() takes 1 positional argument but 2 were given. I remove the input of ui.display() and it works. The runnable code should be:

import math
from time import sleep, time
from blessed import Terminal
import contextlib
from typing import Generator

from dashing import (
    ColorRangeVGauge,
    HBrailleChart,
    HChart,
    HGauge,
    HSplit,
    Log,
    Text,
    VChart,
    VGauge,
    VSplit,
)

@contextlib.contextmanager
def open_terminal() -> Generator:
    """
    Helper function that creates a Blessed terminal session to restore the screen after
    the UI closes.

    t = Terminal()

    with t.fullscreen(), t.hidden_cursor():
