Javascript 角度谷歌地图不会渲染，也不会抛出错误

我是新手，但我认为我一切都对。这是一个非常简单的设置

这是应用程序

var appLocations = angular.module('locations', ['uiGmapgoogle-maps']).config(function(uiGmapGoogleMapApiProvider) {

    uiGmapGoogleMapApiProvider.configure({
        // key: 'I am not providing a key',
        v: '3.17',
        libraries: 'weather,geometry,visualization'
    });
});

appLocations.controller('LocationsController', function($scope, $http) {
    $http.get('/json/locations/')
        .then(function(res){
            $scope.locations = res.data;
        });
});

appLocations.controller('MapController', function($scope, $http) {
    $http.get('/json/locations/')
        .then(function(res){
            $scope.locations = res.data;
        });
    $scope.map = { center: { latitude: 45, longitude: -73 }, zoom: 8 };
});

这是标记

<div class="main1-in" ng-app="locations">
        <div ng-controller="MapController">
            <ui-gmap-google-map></ui-gmap-google-map>
        </div>
        <div class="health-care large-12 medium-11 small-12">
            <h1>Welcome</h1>
            <?php dynamic_sidebar('Welcome')?>

        <div class="location large-12 medium-12 small-12" ng-controller="LocationsController">

            <div class="location-carousel large-12 medium-12 small-12">

                            </p>
                            <small itemprop="telephone">{{location.phoneNumber}}</small>
                            <a href="{{location.permalink}}" itemprop="url">Visit location page</a>
                        </div>
                    </li>
                </ul>
            </div>

        </div>
    </div>

欢迎
位置


{{location.Name}

{{location.address1}}{{location.address2}}

{{location.city}}，

{{location.zip}

{{location.phoneNumber}

控制台中没有错误。应用程序的其余部分渲染，但贴图本身不渲染。任何帮助都将不胜感激

根据文档，您的所有操作都是正确的，除了一件事，您需要提及地图中心和地图的缩放级别，请参见快速入门文档

<ui-gmap-google-map center='map.center' zoom='map.zoom'></ui-gmap-google-map>

或者动态设置访问DOM的高度。

您可以在plnkr.co中做一个工作示例吗？为什么不提供密钥？我的理解是，它们不需要API密钥@cs1193我会看看我能做些什么。所以我试着在plnkr.co上做一个例子，但都没能成功。我正在网上制作一个工作版本，这样你们就可以看了。在此之前，任何帮助都将不胜感激。@AaronBlakeley能给我一些/json/locations的示例内容吗？

.angular-google-map-container { height: 400px; }
