Bootstrap carousel chevron button and slides are not working - bootstrap-carousel

Question

I've pasted my code for a bootstrap carousel below. It doesn't work, but I'm not sure why.
<div id="carouseldiv" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
<li data-target="#carouseldiv" data-slide-to="0" class="active"></li>
<li data-target="#carouseldiv" data-slide-to="1"></li>
<li data-target="#carouseldiv" data-slide-to="2"></li>
<li data-target="#carouseldiv" data-slide-to="3"></li>
<li data-target="#carouseldiv" data-slide-to="4"></li>
<li data-target="#carouseldiv" data-slide-to="5"></li>
</ol>
<div class="carousel-inner">
<div class="item active">
<img src="img/1.jpg" alt="1">
<div class="carousel-caption">
<p>PUBG : King of all games</p>
</div>
</div>
<div class="item">
<img src="img/2.jpg" alt="1">
<div class="carousel-caption">
<p>PUBG : King of all games</p>
</div>
</div>
<div class="item">
<img src="img/3.jpg" alt="1">
<div class="carousel-caption">
<p>PUBG : King of all games</p>
</div>
</div>
<div class="item">
<img src="img/4.jpg" alt="1">
<div class="carousel-caption">
<p>PUBG : King of all games</p>
</div>
</div>
<div class="item">
<img src="img/5.jpg" alt="1">
<div class="carousel-caption">
<p>PUBG : King of all games</p>
</div>
</div>
<div class="item">
<img src="img/6.jpg" alt="1">
<div class="carousel-caption">
<p>PUBG : King of all games</p>
</div>
</div>
</div>
<a class="left carousel-control" href="#carouseldiv" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#carouseldiv" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
<span class="sr-only">Next</span>
</a>
</div>

I compared your code snippet to the one on bootstrap's website.
It looks like you're not using the classes on your div's and spans that Bootstrap needs.
For example you have <div class="item"> when the Boostrap documentation shows <div class="carousel-item">. I also noticed you using glyphicon chevron's when you should be using <span class="carousel-control-prev-icon" aria-hidden="true"></span> and <span class="carousel-control-next-icon" aria-hidden="true"></span>.
Basically, after verifying that Bootstrap is correctly imported, you're going to need to go through the Bootstrap documentation code snippet and your own line-by-line to make sure the CSS classes used are the same. You'll probably find it helpful to start with a 2-slide carousel, rather than a 6-slide carousel.
You didn't post what version of Bootstrap you're using, so I assumed version 4.1 (the latest stable version as I'm writing this).
