“TypeError：无法读取 null 的属性‘ban’

Question

我最近一直在制作一个自动审核机器人。我规定如果此人收到 30 次警告，该人将被禁止。但它却向我展示了一个错误。我试图自己修复它，但不知道问题出在哪里。这是我使用的代码：if (warns.warns.length === 30 && message.member.bannable) { embed.addField(  `⛔ ${message.author.tag} has reached 30 warnings.`,  `**${message.author} has been banned permanently.**`,  true ); setTimeout(function() {  message.member   .send(banemb)   .then((message) => message.member.ban({ reason: '30 warnings' })); }, 1000);}这是我得到的错误：{  "stack": "TypeError: Cannot read property 'ban' of nullat /app/app.js:157:51    at processTicksAndRejections (internal/process/task_queues.js:88:5)"}

Answer 1

改为.then(message =>_.then(msg =>

因为您覆盖了消息变量，所以新message变量是null

setTimeout(function() {

 message.member

  .send(banemb)

  .then((msg) => message.member.ban({ reason: '30 warnings' }));

}, 1000);
