python - 创建从 github 安装的健身房时出现 ModuleNotFoundError

Question

我正在尝试为Kaggle 饥饿的鹅比赛创建一个定制的健身房。我创建了一个并在这里提交。我用命令安装它：

pip install git+https://github.com/Mahesha999/gym-hungrygeese.git

然后尝试创建一个健身房：

import gym
env = gym.make('gym_hungrygeese:hungrygeese-v0')

但它给出了以下错误：

---------------------------------------------------------------------------

During handling of the above exception, another exception occurred:
