【问题描述】：

我正在从 github 存储库做我的第一个不和谐机器人。它连接到不和谐，并登录到服务器，但不会响应!help 命令等。这不是我的代码，所以我对它不是很熟悉，但是命令的代码似乎很好

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张。

【问题讨论】：

您必须包含更多关于尝试做什么的详细信息。 Stack Overflow 不是代码编写服务。我们总是乐于帮助和支持新的编码员，但您需要先帮助自己。您应该尝试自己编写代码。请阅读How to create a Minimal, Reproducible Example 和How do I ask a good question?。
我们不知道，因为我们无法重现问题。而且 Java ≠ JavaScript。

【解决方案1】：

而不是 command.content 使其成为 message.content 以使其工作，因为您尚未定义命令，请不要复制代码。

if(message.content === "!help" ........
