Getting error about php-pinterest-bot

[seregazhuk]

The problem is that you didn't include library files in your script.

[rl421403]

Which file do I need to include.
This is also not working.

<?php

include ( 'src/PinterestBot.php' );

use seregazhuk\PinterestBot\PinterestBot;


$bot = new PinterestBot('mypinterestlogin', 'mypinterestpassword');
$bot->login();

$boards = $bot->boards->my();

echo $boards;

Now the error is.

PHP Fatal error: Class 'seregazhuk\PinterestBot\Request' not found in /var/www/html/pin/src/PinterestBot.php on line 38

Install library via composer and then use composer autoload file.
