大家好，我是 React 的新手，我正在使用 react-places-autocomplete https://www.npmjs.com/package/react-places-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" />
    <meta name="theme-color" content="#000000" />
    <meta
      name="description"
      content="Web site created using create-react-app"
    />
    <link rel="apple-touch-icon" href="%PUBLIC_URL%/logo192.png" />
    <!--
      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`.

      This HTML file is a template.
      If you open it directly in the browser, you will see an empty page.

      You can add webfonts, meta tags, or analytics to this file.
      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`.

【解决方案1】：

您应该在安装任何组件之前加载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 组件中尝试这样的操作：

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>
  )
}

我已经将它添加到 index.html 中，也一样
是在bundle.js之前加载的吗？顺序很重要！您的build 流程如何？你能提供你的index.html 例子吗？
我已经添加了 index.html 请看上面
