必须加载Google Maps JavaScript API库

问题描述

大家好，我是React的新手，我正在使用 react-places-autocomplete （{replaces-autocomplete ），并面对以下error：

Error: [react-places-autocomplete]: Google Maps JavaScript API library must be loaded. See: https://github.com/kenny-hibino/react-places-autocomplete#load-google-library**

我的html包含必要的script标签！

    <script src="https://maps.googleapis.com/maps/api/js?key=*****************&libraries=places"></script>

这是我的Index.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <Meta charset="utf-8" />
    <link rel="icon" href="%PUBLIC_URL%/favicon.ico" />
    <Meta name="viewport" content="width=device-width,initial-scale=1" />

      manifest.json provides Metadata used when your web app is installed on a
      user's mobile device or desktop. See https://developers.google.com/web/fundamentals/web-app-manifest/
    -->
    <link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
    <!--
      Notice the use of %PUBLIC_URL% in the tags above.
      It will be replaced with the URL of the `public` folder during the build.
      Only files inside the `public` folder can be referenced from the HTML.

      Unlike "/favicon.ico" or "favicon.ico","%PUBLIC_URL%/favicon.ico" will
      work correctly both with client-side routing and a non-root public URL.
      Learn how to configure a non-root public URL by running `npm run build`.

      The build step will place the bundled scripts into the <body> tag.

      To begin the development,run `npm start` or `yarn start`.
      To create a production bundle,use `npm run build` or `yarn build`.

解决方法

在安装任何组件之前，您应该加载google maps library！

<!-- Maps library -->
<script src="https://maps.googleapis.com/maps/api/js?key=*****************&libraries=places"></script>
<!-- bundle.js -->
<script src="bundle.js"></script>

您可以在affected组件中尝试类似的操作：

state = {
  gmapsLoaded: false,}

initMap = () => {
  this.setState({
    gmapsLoaded: true,})
}

componentDidMount () {
  window.initMap = this.initMap
  const gmapScriptEl = document.createElement(`script`)
  gmapScriptEl.src = `https://maps.googleapis.com/maps/api/js?key=SECRET_EATING&libraries=places&callback=initMap`
  document.querySelector(`body`).insertAdjacentElement(`beforeend`,gmapScriptEl)
}

render () {
  return (
    <div>
      {this.state.gmapsLoaded && (
        <PlacesAutocomplete />
      )}
    </div>
  )
}
