我正在github存储库中执行我的第一个discord bot。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，所以我对它不是很熟悉，但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 gamen!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

任何帮助都将不胜感激，因为我在这里有点时间紧张。我一点也不熟悉Javascript，所以如果这是一个愚蠢的问题，我很抱歉！

您不应该使用command，而应该使用msg
例如，您编写了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
})
希望这能有所帮助。
