【问题描述】:
我正忙于一个小型条码扫描器应用程序,它有一个可以设置本地 IP 的 SettingsComponent。该应用程序构建没有问题,但是当它部署在 genymotion 模拟器上时,我收到以下错误。即使我将它导入到我的 app.module.ts... 中,它似乎也找不到 SettingsComponent (它被添加到下面的“...NavigatableComponents”代码中的声明数组中)。知道为什么会发生这种情况以及如何解决它吗?
我的错误:
“主”线程上发生未捕获的异常。 java.lang.RuntimeException:无法恢复活动 {org.nativescript.barcodescanner/com.tns.NativeScriptActivity}:com.tns.NativeScriptException: 调用 js 方法 onCreateView 失败
错误:组件设置组件不是任何 NgModule 的一部分,或者该模块尚未导入到您的模块中。 文件:“/data/data/org.nativescript.barcodescanner/files/app/tns_modules/@angular/compiler/bundles/compiler.umd.js,行:17126,列:14

export class SettingsComponent {
ipSaved: boolean;
constructor(private restService: RestService, private appSettingsService: AppSettingsService) {
}
submitIP(ip: string) {
this.appSettingsService.saveLocalIP(ip);
this.restService.init(ip);
this.ipSaved = true;
}
}
