Roulette-v0 step function fails with numpy.random._generator.Generator' object has no attribute 'randint'

Perhaps I'm using the wrong gym version?
If so, how do I find out which version is installed and how to install the correct one?
Thanks for any assistance.

gym.version
<module 'gym.version' from '/usr/local/lib/python3.11/site-packages/gym/version.py'>
gym_toytext
<module 'gym_toytext' from '/usr/local/lib/python3.11/site-packages/gym_toytext/init.py'>

I'm trying to build a Roulette program but self.env.step(action) fails.
Below is a simplified version:

import gym
import gym_toytext

env=gym.make("Roulette-v0")
observation, info = env.reset()
observation
0
action=0
observation, reward, termination, truncation, info = env.step(action)

Traceback (most recent call last):
