在 Python Anywhere 上运行我的 Discord Bot 时出错

Question

我使用 Python 3.6 制作了一个 Discord Bot。它在我的计算机上运行时运行良好，但当我在 PythonAnywhere 上运行它时，我收到了这条消息。我安装了 Discord.py 和所有必要的模块。请帮忙。我不太擅长复杂的编程谈话，也不擅长网络谈话，所以请尽可能简单地回答。这个问题是否只发生在 PythonAnywhere 或所有远程托管站点上？

Answer 1

这是因为 PythonAnywhere 需要 aiohttp websocket 不支持的代理。他们的论坛上有一个关于它的帖子：https://www.pythonanywhere.com/forums/topic/7384/（参见上面@Patrick Haugh 的评论）
