angular - 如何修复 Angular 6 中的 'Google Maps JavaScript API error: InvalidKeyMapError' 错误？

Question

我在我的 Angular 6 应用程序中使用谷歌地图。

我也一直在另一个项目中使用这个谷歌地图。但最近我开始另一个项目并安装 angular agm。然后使用我以前项目使用的 API key 。但它没有用。说'这是一个无效的 key '。所以我得到了新的 API key ，但也有同样的问题。
这是浏览器中显示的问题。

您可能会加载 Google Maps API 两次，请检查您是否在提供程序中加载它

uiGmapGoogleMapApi.then(function(maps) {});

并同时加载脚本标签

<script src="https://maps.googleapis.com/maps/api/js"></script>

尝试删除脚本标签，看看它是否有效。
