这是 const 或 var 的问题。我认为除非我重新编码，否则它不会起作用。这是我的问题：

bot.on('ready', () => {
^

ReferenceError: bot is not defined

这是我的代码：

const Discord = require('discord');
const bot = new Discord.Bot();
const fs = require('fs')
const commandsList = fs.readFileSync('Storage/commands.txt','utf8');
});

bot.on('ready', () => {
  // This event will run if the bot starts, and logs in, successfully.
  console.log(`Bot has started, with ${client.users.size} users, in ${client.channels.size} channels.`);
});

bot.on('message', message => {
    if (message.content === '!ping') {
    	message.channel.send('pong');
  	}
});

bot.on('message', message => {
    if (message.content === '!apply') {
    	message.channel.send('GOGLE STUFF');
  	}
});

bot.on('message', message => {
    if (message.content === '!server') {
    	message.channel.send('LA');
  	}
});

bot.on('message', message => {
    if (message.content === '!do you know dae wae') {
    	message.channel.send('Yes I know dae wae brother');
  	}
});

bot.on('message', message => {
    if (message.content === 'do you have a bot?') {
    	message.channel.send('no');
  	}
});

bot.on('message', message => {
    if (message.content === 'who is the owner') {
    	message.channel.send('FantasmicNerd, duh');
  	}
});

bot.on('message', message => {
    if (message.content === 'can i be staff' || message.content === 'can I be staff?' || message.content === 'can i be staff?') {
    	message.channel.send('Application - lalalalalala');
  	}
});

bot.on('message', message => {
    if (message.content === 'somebody touch my spaghet') {
    	message.channel.send('SOMEBODY TOUCH YOUR SPAGHET!');
  	}
});

bot.on('message', message => {
    if (message.content === 'so how about that airline food') {
    	message.channel.send('HAAHAHAHHAHAHAHHAHAHAHAHAHHAHAHHAHAHAHAHHAHAHAAHAHAHHAHAHAHHAHAHAHAHAHHAHAHHAHAHAHAHHAHA');
  	}
});

bot.on('ready',() => {
    console.log('Bot Launched...')

    bot.user.setStatus('Online')

    bot.user.setActivity('on The Magical')
});

bot.on('message', message => {
    if (message.content === '?help' || message.content === '?Help') {
    	message.channel.send('I have messaged you the commands and prefix.');
  	}
});

bot.on('message', message => {
    if (message.content === '?help' || message.content === '?Help') {
    	message.author.sendMessage(commandsList);
  	}
});

bot.on('ready', function() {
    bot.user.setUsername("The Magical");

// THIS  MUST  BE  THIS  WAY
bot.login('NDA0NjYzNzIwNDQzMzc5NzEy.DUapFw.zjDvPkG4QxZJ1rdxDYaPZEaVpiM');

我到处寻找答案，但似乎没有什么用。当我尝试运行它时，我在 cmd 提示符中看到这个
