Manim exception in text mobject example

I’m trying to run this example from Manim community documentation:

from manim import *

class HelloWorld(Scene):
    def construct(self):
        text = Text('Hello world').scale(3)
        self.add(text)

For some reason I’m getting this error:

TypeError: __init__() got an unexpected keyword argument 'color'

I’m using the latest version of Manim community (0.14.0)

What am I doing wrong?

The full output is:

(Python3.9) C:UsersUserIdeaProjectsGraphConnectivityDemo>manim -pql scene.py HelloWorld

Answer

You could try to upgrade manimpango via pip install -U manimpango. As a workaround, using Tex instead would also work as long as you have LaTeX installed.
