How to install popper.js with Bootstrap 4?

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

with bootstrap 4 I am using this

<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>

and it is working perfectly fine, give it a try

I had problems installing it Bootstrap as well, so I did:

Install popper.js: npm install popper.js@^1.12.3 --save

Install jQuery: npm install [email protected] --save

Then I had a high severity vulnerability message when installing [email protected] and got this message:

run npm audit fix to fix them, or npm audit for details

So I did npm audit fix, and after another npm audit fix --force it successfully installed!

Try doing this:

npm install bootstrap jquery popper.js --save

Bootstrap 4 has two dependencies: jQuery 1.9.1 and popper.js 1.12.3. When you install Bootstrap 4, you need to install these two dependencies.

• Install popper.js: npm install popper.js@^1.12.3 --save
• Install jQuery: npm install [email protected] --save
• Install Bootstrap: npm install [email protected] --save

For Bootstrap 4.1

• npm install popper.js@^1.14.3 --save
• npm install [email protected] --save
• npm install [email protected] --save
