This is the code :
const client = new Discord.Client();
const prefix = ',';
const fs = require('fs');
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('ready', () => {
console.log(`Logged in as ${client.user.tag}!`);
client.user.setActivity('this awesome server', { type: 'WATCHING'}).catch(console.error);
});
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 === 'embed'){
client.commands.get('embed').execute(message, args, Discord);
}
if(command === 'version'){
client.commands.get('version').execute(message, args);
}
});
client.login('My token');```
And the command code:
module.exports = {
name: 'version',
description: "this is the version command",
execute(message, args, Discord){
const exampleEmbed = new Discord.MessageEmbed()
.setColor('#e62e1e')
.setTitle('Leon')
.setDescription('Almost Finished')
.addFields(
{ name: 'Regular field title', value: 'Some value here' },
{ name: '\u200B', value: '\u200B' },
{ name: 'Something', value: 'Nothing', inline: true },
{ name: 'Something', value: 'Nothing', inline: true },
)
.setTimestamp()
.setFooter('See Leon');
message.channel.send(exampleEmbed)
}
}

It seems that you didn't import discord.js.
This is how to do it: place this at the very top:
const Discord = require('discord.js');
