我在我的 Rails 应用程序中设置了一张漂亮的地图。一切正常，但我无法使用 SnazzyMaps 设置地图样式。

这是我的 map.js 文件：

import GMaps from 'gmaps/gmaps.js';

const mapElement = document.getElementById('map');
if (mapElement) { // don't try to build a map if there's no div#map to inject in
  const map = new GMaps({ el: '#map', lat: 0, lng: 0 });
  const markers = JSON.parse(mapElement.dataset.markers);
  const mapMarkers = map.addMarkers(markers);
  mapMarkers.forEach((marker, index) => {
      marker.addListener('click', () => {
        // map.setCenter(markers[index]);
        markers[index].infoWindow.open(map, marker);
      })
    });

  if (markers.length === 0) {
    map.setZoom(2);
  } else if (markers.length === 1) {
    map.setCenter(markers[0].lat, markers[0].lng);
    map.setZoom(14);
  } else {
    map.fitLatLngBounds(markers);
  }
}

import { autocomplete } from '../components/autocomplete';

// [...]
autocomplete();

在 SnazzyMaps 上，他们给出了以下示例。我的问题是，我应该将这段代码的哪一部分插入到我自己的文件中。现在已经尝试了一段时间，但无法使其工作。这是 SnazzyMaps 示例：

<!DOCTYPE html>
<html>
    <head>
        <title>Snazzy Maps Super Simple Example</title>

        <style type="text/css">
            /* Set a size for our map container, the Google Map will take up 100% of this container */
            #map {
                width: 750px;
                height: 500px;
            }
        </style>

        <!--

要使用Gmaps库设置样式，您需要定义样式，然后将其设置为当前地图，如下所示： 

const map = new GMaps({ el: '#map', lat: 0, lng: 0 });
var styles = [
    {
      stylers: [
        { hue: "#00ffe6" },
        { saturation: -20 }
      ]
    }, {
        featureType: "road",
        elementType: "geometry",
        stylers: [
            { lightness: 100 },
            { visibility: "simplified" }
      ]
    }, {
        featureType: "road",
        elementType: "labels",
        stylers: [
            { visibility: "off" }
      ]
    }
];

map.addStyle({
    styledMapName:"Styled Map",
    styles: styles,
    mapTypeId: "map_style"  
});

map.setStyle("map_style");
