在上我得到错误部分的地方添加命令

if(command === "add") { 
if (!message.member.hasPermission("ADMINISTRATOR")) return message.reply("Sorry, you can't do it, you are not an admin!");  
let messageArray = message.content.split(" ");  
let args = messageArray.slice(1);   
var acc = args[1].split(":");   

Answer 1

如果你在nodejs v14中，你可以制作：

if(command === "add") { 
if (!message.member.hasPermission("ADMINISTRATOR")) return message.reply("Sorry, you can't do it, you are not an admin!");  
let messageArray = message.content.split(" ");  
let args = messageArray.slice(1);   
var acc = args[1]?.split(":");

acc未定义，但没有错误。

如果你在nodejs v12中，你可以做一个简单的条件：

if(command === "add") { 
if (!message.member.hasPermission("ADMINISTRATOR")) return message.reply("Sorry, you can't do it, you are not an admin!");  
let messageArray = message.content.split(" ");  
let args = messageArray.slice(1);
if(!args[1]) return;
var acc = args[1].split(":");
