Question

    if (message.content.startsWith(`${prefix2}red`)){
    if (message.member.roles.some(role => role.name === 'Red')) return message.channel.send(`You already has that role `)
    let role = message.guild.roles.find(r => r.name === "Red");
    let member = message.member; 
    message.delete(1)
    member.addRole(role).catch(console.error)
        }   
    })

我需要更改什么？为它工作？

错误是 if (message.member.roles.some(role => role.name === 'Red')) return message.channel.send(`You already has that role `) TypeError: message.member.roles.some is not a function

Answer 1

我假设您正在使用discord.js v12，这就是为什么您的代码无法正常工作的原因。

尝试使用message.member.roles.cache.some(role => role.name === 'Red')代替message.member.roles.some(role => role.name === 'Red')

似乎message.member是未定义的，您可能要检查是否在行会中完成。如果它在公会中，则将返回member属性，如果它不在公会中，则不会。您要做的是检查邮件是否是从公会发送的，请尝试以下代码：

client.on("message", message => {
  // `!` means `non-existent` or `is not`, and if the user sends the message from a guild  
  // this will not be triggered, since we know they are in, rather than not in, but, if
  // it was sent outside of a guild, say a DM, then it will return the command, not trigerring
  // any errors or such.
  if (!message.guild) return;

  // This will not allow this command to be triggered by the bot itself, since it may
  // return a loop.
  if (message.author === client.user) return;

  // If the author of the message is a bot, then return, since bots can be used to spam
  // and this will also spam your bot's API request. Webhooks work the same way.
  // `||` means `or` if you didn't know.
  if (message.author.bot || message.webhookID) return;

  // Checks if the member has the role "ROLE NAME", and if they do, return.
  if (message.member.roles.cache.some(role => role.name == "ROLE NAME")) return;
  // code...
});

TypeError：message.member.roles.some不是函数
