#keep_alive.keep_alive()
token = os.environ.get("TOKEN")
bot.run(token, bot=True)

不要说令牌不存在我知道它不存在。

但随后我收到此错误消息：

Traceback（最近一次调用最后一次）： 文件“main.py”，第 137 行，在 async def on_message（消息，成员：discord.Member，*，角色：discord.Role）： 文件“/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/core.py”，第 1246 行，在装饰器中 self.add_command（结果） 文件“/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/core.py”，第 1138 行，在 add_command 引发 CommandRegistrationError(command.name) discord.ext.commands.errors.CommandRegistrationError：命令 on_message 已经是现有命令或别名。

我不知道这意味着什么，请比我更有知识的人指导我完成这个 LOL。

【问题讨论】：

我认为不同的功能需要不同的名称

所以你的意思是async def on_message(message, member: discord.Member, *, role: discord.Role)在括号内使用不同的函数？

尝试将其称为 on_message1、on_message2 等等：async def on_message1(message, member: discord.Member, *, role: discord.Role)

好的，谢谢，我试试看！

您使用的是 repl.it 版本的 discord.py 吗？重写中没有bot.say。

【参考方案1】：

感谢 jacob，代码现在可以工作了！
