我有一个使用 Angular Google Maps 来显示位置的应用程序。一开始我可以显示地图，但是有一段时间（可能我已经修改了一些东西）我收到以下错误：

ERROR Error: Uncaught (in promise): Error: StaticInjectorError[NgZone]: 
StaticInjectorError[NgZone]:

我的代码是：app.module.ts：

import { AgmCoreModule } from '@agm/core';

imports AgmCoreModule.forRoot({apiKey:'...'})

我的组件.html

<agm-map [latitude]="lat" [longitude]="lng" [zoom]="zoom">
    <agm-marker [latitude]="lat" [longitude]="lng">
        <agm-info-window>
            <div>
                my text
            </div>
        </agm-info-window>
    </agm-marker>

我将衷心感谢您的帮助！

您可以NgZone手动提供：

import { NgZone } from '@angular/core';

@NgModule({
    providers: [
        // ...
        { provide: NgZone, useFactory: () => new NgZone({}) }
    ]
})

您需要将 peerDependencies 添加到您正在使用的所有库中。

还可以通过从导入中删除每个模块来检查是哪个模块导致了问题。这link应该会有所帮助。
