简而言之：我用JavaScript制作了一个discord机器人，并用JSHint对其进行了检查，然后在node.js上运行了它。 问题：每次我运行漫游器时，都会收到“未定义msg”错误
我发现已经回答了问题（Question 1，Question 2），但我查看了他们评论中列出的解决方案，就像评论者说的那样。
注意：node.js服务器在Android手机上，并且我已经在其上安装了discord.js。
我的机器人的源代码：
const Discord = require('discord.js');
const client = new Discord.Client();
var delayed = [];
var funcs = {
clean: function(text) {
var temp = "";
text = text + "";
for (var i = 0; i < text.length; i++) {
if (text.charAt(i) != "_" && text.charAt(i) != "*" && text.charAt(i) != "`" && text.charAt(i) != " ") {
temp = temp + text.charAt(i);
}
}
return temp.toLowerCase();
},
log: function(logthat, cmddude) {
console.log(Date().slice(4, 24) + " | " + logthat + " | " + cmddude + "\n");
},
cook: function(cookthishex) {
cookthishex = cookthishex + '';
var returning = '';
for (var i = 0; i < cookthishex.length; i += 2) {
returning += String.fromCharCode(parseInt(cookthishex.substr(i, 2), 16));
}
return returning;
},
random: function(low, high) {
return Math.round(Math.random() * (high - low)) + low
},
delay: function(userid) {
delayed.push(userid);
setTimeout(function(Argument) {
var temp = delayed[delayed.indexOf(Argument)];
delayed[delayed.indexOf(Argument)] = delayed[delayed.length];
delayed[delayed.length] = temp;
delayed.pop();
}, 1000, userid);
},
split(argtext) {
var splitlist = [], splittext = "";
for (var i = 0; i < argtext.length; i++) {
if (argtext.charAt(i) === " ") {
splitlist.push(splittext);
splittext = "";
} else {
splittext = splittext + argtext.charAt(i);
}
}
if (splittext.charAt(splittext.length - 1) === " ") {
splitlist.push(splittext);
}
return splitlist;
}
};

答案 0 :(得分：0)
您的ready事件：
client.on('ready', () => {
console.log("Logged in as ${client.user.tag}!");
funcs.log("activated");
var reacttocomment = true;
if (message.guild.roles.find(x => x.name == "No Bruh")) {} else{
msg.guild.createRole({
name: "No Bruh",
color: "0xf0f0f0",
mentionable: false
}, "Required role to make the 'bruh!doreact' and 'bruh!noreact' commands work.");
}
});
使用两个变量message和msg都没有在该范围内定义（您可能希望从准备事件中删除哪个消息？）。如果您的漫游器仅在一个公会中，请考虑显式获取公会：
client.on('ready', () => {
console.log("Logged in as ${client.user.tag}!");
funcs.log("activated");
var reacttocomment = true;
if (client.guilds.get("someguildID").roles.find(x => x.name == "No Bruh") == null) {
client.guilds.get("someguildID").createRole({
name: "No Bruh",
color: "0xf0f0f0",
mentionable: false
}, "Required role to make the 'bruh!doreact' and 'bruh!noreact' commands work.");
}
});
请注意，在代码中的多个位置，您将用户ID与数字文字进行了比较，例如在这里：
if (delayed && msg.author.id !== 492665478687490048) return;
但是，msg.author.id是一个字符串，而不是数字-这是有充分的理由的，因为JavaScript无法正确处理这么大的数字。由于精度损失，它们将不可预测地四舍五入，并且由于您指定了严格的类型检查!==，因此无论如何比较都将失败。进行比较时，将您的ID指定为字符串：
if (delayed && msg.author.id !== "492665478687490048") return;
