我有問題，我的代碼正在顯示類型錯誤：無法讀取暫停命令未定義的屬性“執行”。所有其他命令都工作正常。讀取文件。client.commands = new Discord.Collection();const commandFIles = fs.readdirSync('./commands/').filter(file => file.endsWith('.js'));for(const file of commandFIles){    const command = require(`./commands/${file}`);    client.commands.set(command.name, command);}client.on('message', msg => {    if (!msg.content.startsWith(prefix) || msg.author.bot) {        return;    }    const args = msg.content.slice(prefix.length).trim().split(/ +/);    const command = args.shift().toLowerCase();    if (command === 'ping') {        client.commands.get('ping').execute(msg, args);    } else if (command === 'userinfo') {        client.commands.get('userinfo').execute(msg, args);    } else if (command === 'delete') {        const amount = parseInt(args[0]) + 1;        if (isNaN(amount)) {            return msg.reply('Enter a valid number.');        } else if (amount <= 1 || amount > 100) {            return msg.reply('Enter a number between 1 and 99.');        } else {            msg.channel.bulkDelete(amount, true).catch(err => {                console.error(err);                msg.channel.send('There was an error trying to delete messages');            });            msg.channel.send(`Deleted ${args} messages.`);        }    } else if (command === 'p' || command === 'play') {        client.commands.get('play').execute(msg, args);    } else if (command === 'pause') {        client.commands.get('pause').execute(msg);    }});如果我復制代碼并粘貼相同的代碼，Client.on它可以正常工作，但在使用 with 時顯示錯誤module.exports。有什么辦法可以解決這個問題嗎？
