i work in pc local and i don't use any server and i use chrome browser

i have error : Uncaught SyntaxError: Cannot use import statement outside a module

`<script src="jquery-3.2.1.min.js"> </script>

<script src="https://unpkg.com/merge-images"></script>

<script> import mergeImages from 'merge-images'; mergeImages(['/body.png', '/eyes.png', '/mouth.png']) .then(b64 => document.querySelector('img').src = b64); // data:image/png;base64,iVBORw0KGgoAA... </script> `

I thought it was me not doing things properly, I was about to go crazy!
I have other errors:

index.js:22 Uncaught (in promise) TypeError: Cannot read property 'constructor' of undefined

    at index.js:22
    at new Promise (<anonymous>)
    at index.js:20
    at Array.map (<anonymous>)
    at index.js:20
    at new Promise (<anonymous>)
    at mergeImages (index.js:12)

If I don't use the import module part, please if someone has any insight on this it would be huge help
