How to install popper.js using Bootstrap 4?

Question

From what I've read so far, popper.js is a big problem with Bootstrap 4. I can't get it to work. I keep getting this error:

Error: Popper.js ( https://popper.js.org ) is required for the bootstrap dropdown list

I tried installing CDN and NPM. The same result. At the bottom of my HTML file, I have this for installing NPM:

<script src="js/jquery.min.js"></script>
<script src="js/popper.min.js"></script>
<script src="js/tether.min.js"></script>
<script src="js/bootstrap.min.js"></script>

Then I tried this for CDN:

<script src="/js/jquery.min.js"></script>
<script src="/js/tether.min.js"></script>
<script src="https://cdnjs.com/libraries/popper.js"></script>
<script src="/js/bootstrap.min.js"></script>

Any ideas what I'm doing wrong?

https://cdnjs.com/libraries/popper.js does not look like the correct src for popper, it does not specify a file

<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js" integrity="sha384-b/U6ypiBEHpOf/4+1nzFpr53nxSS+GLCkfwBdFNTxtclqqenISfwAzpKaMNFNmj4" crossorigin="anonymous"></script>
