最近我一直在用python编写我的bot，因为我是bot的初学者等等，我想做一个meme命令，因为meme是bot的目标，当我执行memr命令时，它说一切都很好，但是当有人运行meme命令，它只是说"discord.ext.commands.errors.CommandInvokeError:命令引发了一个异常:NameError:名称'get'未定义。我不明白为什么会这样。我相信StackOverflow的力量!下面是我的代码:

在函数meme中，您正在调用函数get以从某些URL获取数据。但是，函数get在任何地方都没有定义，导致错误NameError: name 'get' is not defined。您可能需要从requests模块导入它。
将以下行添加到文件顶部:
from requests import get
