I really can\'t get it to send immediately either. It only sends the welcome message when the user sends a message in the server. That\'s also when the error finally appears.

Answer 1

该错误表明message.guild是null。这可能发生在部分消息或来自DM的消息上。

如果邮件是部分邮件，则message.partial将是true。要获取其余消息，请运行message.fetch().then(fullmessage => {...})。

message.channel.type === 'dm'可以告诉您消息是否来自DM。

Answer 2

我建议您添加

if(message.channel.type === 'dm') return message.reply('This command does not work in DMs')

到命令开头，它应该防止出现这种情况。

无法读取null的属性“角色”。加入服务器时向用户添加角色
