我正在创建一个使用 react-google-maps 的网络,但遇到了一堆未定义的错误。我是 react/js 世界的新手,所以任何帮助都将不胜感激。这是确切的错误:

看起来我没有正确导入谷歌地图,但看看这个例子,它不应该有。有任何想法吗?

你可以试试这个 new window.google.maps
这个对我有用!
例子:
<Marker
icon={{
url:"../../assets/img/carz.png",
anchor: new window.google.maps.Point(10, 10),
scaledSize: new window.google.maps.Size(20, 20)
}}
/>

你错过了生命周期和谷歌的导入。在示例中,您可以看到,
const { compose,withProps,lifecycle } = require("recompose");
并且示例中没有提到 google 的导入,但也应该导入。
关于导入 google,它与 eslint 验证有关,而不是 JS。做以下更改:
PlacesAutocomplete.js 第 1 行:
/*global google*/

^ 这将向 eslint 声明 google 是一个全局名称,并将在运行时可用。有关更多信息,您可以浏览此git 页面
