Question

我使用此代码检查了我的漫游器中的角色，但是由于某种原因，我得到了一个错误。

client.on("message", message => {
 if (message.member.roles.cache.some(role => role.name == "ROLE NAME")) return;
 // code...
});

错误如下：

TypeError: Cannot read property 'roles' of null

有人有解决方案吗？

看来message.member是undefined，您可能想检查一下是否在行会中完成。如果它在行会中，它将返回member属性，如果不是，则不会。您要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...
});
