try adding the required javascript libraries that Bootstrap uses in between the head tags at the top of your html file.

A link to the documentation Bootstrap provides explaining how to get started.
https://getbootstrap.com/docs/4.0/getting-started/introduction/
I hope this helps

I created an example on codepen based on bootstrap document
The example demonstrates html, css, js codes to make the carousel work.
$('.carousel').carousel()
Please double check if you add required libraries including
jquery,
bootstrap.js
bootstrap.css.
I added them through Pen Settings.

Why does my Bootstrap carousel only move once?

I'm trying to implement a Bootstrap Carousel into my website however I am having an issue with it where it will only move once and will become unresponsive. I've checked the ordering of the files and that doesn't seem to be an issue. So this has left me stumped on what is causing my issue.
HTML:
<div class="container bg-secondary" id="projectContainer">
<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">

The primary problem is that you were one indicator short. The script was erroring when it tried to find the last one.

You seem to be missing -bs in your data attributes. See the docs.
Also, no Bootstrap library is going to call for onclick attributes in the markup. That's what the data attributes do.

How can images inside Boostrap Carousel have the same width?

This is actually a copy paste from the bootstrap website, I have also tried many other things, and to be honest I am struggling to understand how can these pictures have the same size. If you click next on the carousel you will see that the height is always different!
So how can I do it? I have tried to change the properties of the inner carousel, the div that I created, the different divs, but nothing happens. Especially when I use my own images the size is always weird.

There is a class w-100 in every image which is bootstrap default class for width: 100%. So it will automatically take full width. If you want the heights same, there are 2 ways for it. (1) You must update same width and height images or make the background-image and give the div width:100% and specify its height.
Thanks me later.

Bootstrap example Carousel code not switching slides

I've been researching for over an hour and I cannot get this example code from the Bootstrap website for a Carousel working... the only thing I changed are the image sources. What am I doing wrong? If it helps, this will be in a component in an Angular project.
<div id="ourCarousel" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
<li data-target="#ourCarousel" data-slide-to="0" class="active"></li>
<li data-target="#ourCarousel" data-slide-to="1"></li>
<li data-target="#ourCarousel" data-slide-to="2"></li>
</ol>
<div class="carousel-inner">
<div class="carousel-item active">
<img class="d-block w-100" src="..." alt="First slide">
</div>
<div class="carousel-item">
<img class="d-block w-100" src="..." alt="Second slide">
</div>
<div class="carousel-item">
<img class="d-block w-100" src="..." alt="Third slide">
</div>
</div>
<a class="carousel-control-prev" href="#ourCarousel" role="button" data-slide="prev">
<span class="carousel-control-prev-icon" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="carousel-control-next" href="#ourCarousel" role="button" data-slide="next">
<span class="carousel-control-next-icon" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>
I know that Bootstrap is loading because the first image is showing along with the controls and indicators are there -- the only thing is that they're not responsive.
I put the below code in the main app component, which from there the carousel component is called.

I also tried adding this before and after the code above...
<script>
$("#ourCarousel").carousel();
</script>
I feel like I've done everything imaginable to get it to work, am I missing any important steps?

I tried, but it doesn't seem to be a problem. Guess javascript cannot select html.
OR
$(document).ready(function() {
wait for the document to load.
$("#ourCarousel").carousel()
})
$("#ourCarousel").carousel()

What I ended up doing is putting the above code (waiting for the document to be ready) and moving the imports of Bootstrap from the module with the carousel to index.html. Thanks!

bootstrap carousel image height

i'm having some problems with the images in bootstrap v4 image carousel. If i scale down the browser width the height of image stays the same but the width of image getting smaller so the image gets very stretched out on the height.
I have been looking at similar threads here on stackoverflow and tried everything i found in the comments but it still does not work. So i decided to make a new thread about this.
Here is a codepen link https://codepen.io/anon/pen/owNyyx but i paste the code here too if you do not wish to visit codepen :)
So here is the code i have
<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
<li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
<li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
<li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
</ol>
<div class="carousel-inner" role="listbox">
<div class="carousel-item active">
<img class="d-block img-fluid" src="images/image1.png" alt="First slide">
<div class="carousel-caption d-none d-md-block">
<h3>Random Title for image1</h3>
<p>Random description1</p>
</div>
</div>
<div class="carousel-item">
<img class="d-block img-fluid" src="images/image2.png" alt="Second slide">
<div class="carousel-caption d-none d-md-block">
<h3>Random title for image2</h3>
<p>Random description2</p>
</div>
</div>
<div class="carousel-item">
<img class="d-block img-fluid" src="images/image3.png" alt="Third slide">
<div class="carousel-caption d-none d-md-block">
<h3>Random title for image3</h3>
<p>Random description3</p>
</div>
</div>
</div>
<a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">
<span class="carousel-control-prev-icon" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
<span class="carousel-control-next-icon" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>

It's because the img parent, .carousel-item is display: flex and the img is a flex-child, so it's "stretching" via the default align-items: stretch on the parent.
A number of ways you can fix this. Easiest is probably to give align-items a value other than stretch.
Or if you don't want to apply custom CSS and keep your changes in the markup, wrap each img in a block element like div or figure or whatever works for your site.
.carousel-item {
align-items: flex-start;
}

Set .img-fluid to witdth: 100% or width: inherit. Then slider would be full width.
.img-fluid{
width: inherit;
