    if(!message.content.startsWith(prefix) || message.author.bot) return;

    const command = args.shift().toLowerCase();

    if (command === 'ping'){
        client.commands.get('ping').execute(message, args);
    }
    if (command == 'youtube'){
        client.commands.get('youtube').execute(message, args);
    }
    if (command == 'instagram'){
        client.commands.get('instagram').execute(message, args);
    }
});

Answer 1

更改此行：

if (command === 'ping'){
    client.commands.get('ping').execute(message, args);
}

到这一行：

if (command == 'ping'){
    client.commands.get('ping').execute(message, args);
}

Answer 2

尝试改变

(command === 'ping')

至

(command == 'ping')
