财产＆＃39; readFiles＆＃39;是私人的，只能在课堂上访问＆＃39; ImageUploadDirective＆＃39;

Question

            MapComponent,
            Add_address,Add_City,Add_District,Add_sub_urbans
             ],

        imports: [AgmCoreModule.forRoot({
              apiKey: "Key",
              libraries: ["places"]
                }),
                 BrowserModule,
