我不断收到错误：无法读取未定义的属性“执行”答案

【问题标题】：I keep on getting the error: cannot read property 'execute' of undefined我不断收到错误：无法读取未定义的属性“执行”

【问题描述】：

const Discord = require('discord.js');

const client = new Discord.Client();

const prefix = '-';

const fs = require('fs');

client.command = new Discord.Collection();

const commandFiles = fs.readdirSync('./commands/').filter(file => file.endsWith('.js'));
for (const file of commandFiles) {
    const command = require(`./commands/${file}`);

    client.command.set(command.name, command);
}

client.once('ready', () => {
    console.log('Primio Has Activated :)');
});

client.on('message', message => {
    if(!message.content.startsWith(prefix) || message.author.bot) return;

const args = message.content.slice(prefix.length).split(/ +/);
const command = args.shift().toLowerCase();

    if (command === 'flip') {
        client.command.get('flip').execute(message, args,);

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


client.login('token');

我不断收到错误提示：

【问题讨论】：

看起来client.command.get('flip') 返回未定义。

标签： javascript node.js discord.js

【解决方案1】：

嘿，如果您使用这样的命令处理程序，您需要向我们展示 flip.js。开始时，flip.js 需要位于文件夹名称 commands 中，然后在文件中您需要添加以下代码： module.exports ={ name:'flip' desciption: 'your comment' execute(message,args,Discord){your code here}} 您犯错的第二件事是执行中的 , 到目前为止，您的代码应该看起来像这样if (command === 'flip') { client.commands.get('flip').execute(message, args, Discord); 如果您仍然收到错误，这可能意味着您的执行（消息、参数、不和谐）与 flip.js 中的不同。如果问题解决了给我反馈:D
