I try to edit CSS stlye of Tippy.js. So I npm install tippy and import it to my html like this

<script src="/min/tippy.js/umd/index.all.js"></script> 

But, it has some error.

Uncaught TypeError: Popper is not a constructor
    at createPopperInstance (createTippy.ts:677)
    at mount (createTippy.ts:694)
    at Object.show (createTippy.ts:961)
    at new_control.js:128
    at Array.forEach (<anonymous>)
    at createGraph (new_control.js:101)
    at Object.success (new_control.js:6)
    at u (jquery.min.js:2)
    at Object.fireWith [as resolveWith] (jquery.min.js:2)
    at k (jquery.min.js:2)

So, I have tried to npm install popper in my directory working file but,it's not work at all. Did I miss something?

Nice try although i would recend after installing popper by npm install, try to add this to your HTML file.
