我正在嘗試使用谷歌地圖和插件https://www.npmjs.com/package/vue2-google-maps構(gòu)建一個(gè) vue 谷歌地圖組件。我已經(jīng)使用 npm 安裝了插件，并且當(dāng)我的 googleMap.vue 組件開(kāi)始工作時(shí)：-->        <!-- :center="{lat: 30.08674842, lng: -97.29304982}" -->        <GmapMap        :center="{lat: latitude, lng: longitude}"        :zoom="15"        map-type-id="terrain"        style="width: 500px; height: 300px"      >      </GmapMap>      </span>      </v-flex>    </v-container>  </div></template><script>  var latitute = 30.08674842  var longitude = -97.29304982  import {    gmapApi  } from 'vue2-google-maps'  export default {    // name:'myMap'    latitute:latitute,    longitude:longitude,   }<當(dāng)我運(yùn)行這個(gè)時(shí)，我得到： ERROR  [Vue warn]: Property or method "longitude" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property.我怎樣才能解決這個(gè)問(wèn)題？
