Node.js Discord.js UnhandledPromiseRejectionWarning：TypeError：无法读取未定义的属性“ calculatedPosition”

Question

我正在使用discord.js，正在执行ban命令，但出现以下错误：UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'calculatedPosition' of undefined

我的代码是：

let banUser = message.guild.member(message.mentions.users.first())
let bannerHighRole = message.member.highestRole.calculatedPosition;
let getBannedHighRole = banUser.highestRole.calculatedPosition;
if (bannerHighRole < getBannedHighRole) return message.reply("You cannot ban users that have higher roles than you!")
if (bannerHighRole = getBannedHighRole) return message.reply("You cannot ban users that have same highest role!")

如何解决此错误？ 我正在Discord.js v12上运行该机器人

这必须是v11或更高版本的代码，请检查文档以更新您的其他代码，但无论如何：

他们已经将很多fetchMessages之类的camelCase函数更改为messages.fetch之类的东西，可能会很有用。

// you can use message.mentions.members instead of converting a user
let banUser = message.mentions.members.first();
let bannerHighRole = message.member.roles.highest.position;
let getBannedHighRole = banUser.roles.highest.position;
if (bannerHighRole < getBannedHighRole) return message.reply("You cannot ban users that have higher roles than you!");
//you had x = y, which is an assignment
if (bannerHighRole === getBannedHighRole) return message.reply("You cannot ban users that have same highest role!");

还看到了完整的代码，在计算所有这些代码之前，您应该检查用户是否具有mod / admin。
