I just need to add bootstrap 4, so I can use it in my template.
In Magento 1 I could just add all the scripts to the head and then I could use bootstrap.
So I tried it:
app\design\frontend\company\base\Magento_Theme\layout\default_head_blocks.xml
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<head>
<!-- Latest compiled and minified CSS -->
<link src_type="url" rel="stylesheet" src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" />
<!-- Latest compiled JavaScript -->
<script src_type="url" src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
</head>
</page>
But I get Uncaught Error: Mismatched anonymous define() module in the console.
I also tried it like seen here. I get "Uncaught Error: Script error for: bootstrap"
