Question

我正在从 github 存储库做我的第一个不和谐机器人。它连接到 discord 并登录到服务器，但不会响应 !help 命令等。这不是我的代码，所以我不是很熟悉，但命令的代码似乎没问题。

if (command.content === '!create' && !game) {
  createGame(command)
} else if (command.content === '!start' && game && !game.started) {
  command.delete()
  game.start()
} else if (command.content === '!help') {
  command.channel.send(`!create: Create a new game\n!start: Start the game previously created`)
}if (message.content === 'restartthebot') {
  if (message.author.id !== 'Owners ID') return;
  message.channel.send('Restarted.').then(() => {
  process.exit(1);
})
};

我在终端控制台中收到此错误消息

任何帮助将不胜感激，因为我在这里有点时间紧缩。我对 Javascript 一点也不熟悉，所以如果这是一个愚蠢的问题，我很抱歉！

Answer 1

您不应该使用 command，而应该使用 msg

例如，你写了 command.channel.send("heck yeah I'm here"); 相反，它应该是 msg.channel.send("heck yeah I'm here");

而不是：

client.on('message', command => {
//code here
})

应该是：

client.on('message', msg => {
//code here
})

希望这有帮助。
