使用OpenAI Gym库时，安装Atari环境可能会遇到一些依赖问题，尤其是在Mac OS X系统上

问题背景：

I'm new to OpenAI gym. I've successfully installed OpenAI gym on my Mac OS X (High Sierra 10.13.3) laptop and made a DQN for the CartPole game. I'm trying to install the Atari dependency to use MsPacman. I tried:

我是OpenAI Gym的新手。我已经成功在我的Mac OS X（High Sierra 10.13.3）笔记本电脑上安装了OpenAI Gym，并为CartPole游戏制作了一个DQN（深度Q网络）。我现在正尝试安装Atari依赖项以使用MsPacman。我尝试了以下方法：

python 复制代码

$ pip install gym[atari]

And get that Atari is successfully installed (I see atari_py in the same directory as gym and atari within the gym directory). But when I run the code I get:

并且我已经成功安装了Atari（我在gym目录中的与gym和atari相同的目录下看到了atari_py）。但是当我运行代码时，我得到了：

python 复制代码

raise error.DependencyNotInstalled("{}. (HINT: you can install Atari dependencies by running 'pip install gym[atari]'.)".format(e))
gym.error.DependencyNotInstalled: No module named atari_py. (HINT: you can install Atari dependencies by running 'pip install gym[atari]'.)

If I add: 如果我添加

python 复制代码

import atari_py

to the source file, I get: 添加到源文件，后得到如下信息

python 复制代码

File "dqn.py", line 9, in <module>
    import atari_py
ImportError: No module named atari_py

Edit: as per the documentation, I also tried

编辑：根据文档，我也尝试了

python 复制代码

pip install -e '.[atari]'

And I get: 得到以下信息

python 复制代码

Directory '.' is not installable. File 'setup.py' not found.

Any thoughts?

有什么想法吗？
