Prism.js Line-Numbers Plugin not working

[s3tupw1zard]

Hi,
I added Prism.js to my Ghost Blog with simply installed but the Line-Numbers Plugin isn't working for code blocks.

This is how I'm trying to add line-numbers:

<div class="code-block">
    <pre><code class="language-html line-numbers">
    &lt;div class="code-block"&gt;
    &lt;pre&gt;&lt;code class="language-javascript"&gt;
    &lt;!-- Dein Code hier --&gt;
    &lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;
    </code></pre>
</div>

This is what I added to my site footer:

<script>
    document.addEventListener('DOMContentLoaded', function() {
        document.querySelectorAll('pre > code.line-numbers').forEach(function(code) {
            code.classList.add('line-numbers');
        });
        Prism.highlightAll();
    });
</script>

This are the libraries and plugins I added from prism.js:

I added all libraries and plugins I'm using here for completeness.

This is what it looks like when I go to the preview of my blog post:

There should be line numbers at the beginning of every line. This is working on other themes, like the default one.

Thanks

Hi

1. Replace this code

if (docSelectorAll('code[class*=language-]').length && typeof prismJs !== 'undefined') {
    const $code = docSelectorAll('code[class*=language-]')

    $code.forEach(element => {
      element.classList.add('line-numbers')
    })

    loadScript(prismJs)
  }

simply/src/js/post.js

Lines 73 to 75 in b8f23f1

	if (docSelectorAll('code[class*=language-]').length && typeof prismJs !== 'undefined') {
	loadScript(prismJs)
	}

2. Load the necessary plugins

import Prism from 'prismjs'
import 'prismjs/plugins/autoloader/prism-autoloader'
// here Plugins
import 'prismjs/plugins/line-numbers/prism-line-numbers'
// Other Plugins
// import 'prismjs/plugins/toolbar/prism-toolbar'
// import 'prismjs/plugins/copy-to-clipboard/prism-copy-to-clipboard'
// import 'prismjs/plugins/show-language/prism-show-language'

simply/src/js/prismjs.js

Lines 6 to 7 in b8f23f1

	import Prism from 'prismjs'
	import 'prismjs/plugins/autoloader/prism-autoloader'

3. Compress for production yarn run prod

Okay, I edited my fork of your repo as you described, but the line-numbers are still not showing up.

You also have to add your line-numbers classes
