有关事物的信息：我尝试使用本教程创建警告命令：https://www.youtube.com/watch?v=vk_FF887N0o。我一步一步地遵循它两次，它创建了一个角色，但在那之后它没有修复。它使角色，然后它表明我的其他东西是未定义的。如果我输入 !!warn （!! 是前缀）它会使我在代码中声明的 3 个角色，但它给出了错误。我再次尝试执行 !!warn 并且它产生了更多的角色。我对为什么会发生这种情况感到有些困惑，如果您有任何想法，请告诉我。该机器人也由 heroku 托管（如果有帮助的话）。我还尝试在没有数据库的情况下制作角色命令，看起来它可以正常工作，只是因为某些奇怪的原因，它说角色和角色未定义。

机器人信息：这是一个简单的机器人，包括一个命令和事件处理程序（在代码顶部执行之前忽略这些部分）。

Answer 1

在查看了一些代码和错误消息之后。

我得出的结论是问题出在这条线上：

if (mentiondMember.role.cache.has(warnRole1.id)) punishment = 2;
if (mentiondMember.role.cache.has(warnRole2.id)) punishment = 3;
if (mentiondMember.role.cache.has(warnRole3.id)) punishment = 4;

问题 1：

变量“mentiondMember”是未定义，您可能需要检查您的：

const mentiondMember = message.guild.members.cache.get(args[0]) || message.mentions.members.first();

并确保它们返回有效的GuildMember 对象。

提示： 如果您正在使用调试器，您可以在“mentiondMember”附近放置一个断点，以便轻松检查变量！

问题 2：

您正试图从“mentiondMember”访问不存在的对象“角色”！

我不确定您的 Discord.JS 版本，但在 Discord.JS 版本 12.5.3 的文档中：

A GuildMember doesn't have "role" properties, instead they have the "roles" properties !

所以我认为您需要将该行更改为：

if (mentiondMember.roles.cache.has(warnRole1.id)) punishment = 2;
if (mentiondMember.roles.cache.has(warnRole2.id)) punishment = 3;
if (mentiondMember.roles.cache.has(warnRole3.id)) punishment = 4;

（节点：14808）未处理的承诺拒绝警告：类型错误：无法读取未定义的属性“角色”
