jquery.js and jquery.keyframes.js are not found when using NPM

I’m having trouble using jquery and jquery.keyframes. I use NPM and the js files are stored in the node_modules folder while the html files are stored in the public folder. For some reason the html file cannot find the js files when I use this code:

<script src="../node_modules/jquerykeyframes/dist/jquery.keyframes.js"></script>
<script src="../node_modules/jquery/dist/jquery.js"></script>

I’ve tried a few alternatives but nothing has worked. What am I doing wrong?
