ReactJS中的GTM脚本

Question

我已将此脚本放在index.html

的body标签中

<noscript>
      <iframe src="//www.googletagmanager.com/ns.html?id=GTM-KMXH6S"
              height="0" width="0" style="display:none;visibility:hidden"></iframe>
    </noscript>
    <script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
      new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
      j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
      '//www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
    })(window,document,'script','dataLayer','GTM-XXXXXX');
    </script>

但是它保持原样并且GTM的脚本从不加载。我还需要做什么？
