问题描述
我一直在使用 PyCharm 学习一些强化学习，并且我在健身房 LunarLanding 环境中学习了使用 deep q 的教程，(https://www.youtube.com/watch?v=wc-FxNENg9U&t=1428s)，
这是 python 文件创建的 GitHub 链接 (https://github.com/philtabor/Youtube-Code-Repository/blob/master/ReinforcementLearning/DeepQLearning/main_torch_dqn_lunar_lander_2020.py)
我目前在运行时遇到此错误：
Traceback (most recent call last):

AttributeError: module 'gym.envs.Box2d' has no attribute 'LunarLander'
我已经寻找了此修复程序的答案，其中包括 pip install Box2D，但是当我运行时，我遇到了更多问题。第一个是没有安装 SWIG，但是我解决了这个问题，现在我收到了这个错误：

这完全让我感到困惑，因为错误告诉我现在说要获取不同版本的 Visual Studio 代码，但我使用的是 PyCharm。
我已经为此苦苦挣扎了一段时间，如果有人知道解决代码的主要错误或 pip 安装错误，那就太好了。
如果您需要更多信息，请告诉我。
