Use environement variable in index.html

I'm using angular and I want to use an environment variable in my index.html for google analytics. I tried like this :

    import {environment} from "./environments/environment";
<!-- End Google Tag Manager (noscript) -->
<script async src="" + environment.googleAnalytics></script>
    window.dataLayer = window.dataLayer || [];
    function gtag(){dataLayer.push(arguments);}
    gtag('js', new Date());

    gtag('config', environment.googleAnalytics);
