[Kivy] ModuleNotFoundError: No module named 'kivy'

[Exsul]

I've installed Kivy to the specifications given in this documentation and this video, but when I try to run the following code,

import kivy
kivy.require('1.0.8')

from kivy.app import App
from kivy.uix.button import Label

class HelloKivy(App):

    def build(self):
        return Label(text="Hello, Kivy.")

helloKivy = HelloKivy()

helloKivy.run()

I get this error:

Traceback (most recent call last):
File "C:/Users/[USERNAME]/PycharmProjects/practice/kivytut.py", line 1, in <module>
import kivy
ModuleNotFoundError: No module named 'kivy'
