我对这个问题感到很困惑，而且这似乎不是一个常见问题。我正在运行一个构建 NativeScript Angular 项目，我打算使用相同的代码库构建一个网站、iOS 和 Android。我大约一年前开始了这个项目，然后又回来了。首先，我花了一些时间更新所有包。但是，当运行 ns debug ios 时，我遇到了此错误。
ERROR in Error during template compile of 'AppRoutingModule'
Function calls are not supported in decorators but 'NativeScriptRouterModule' was called.
Unexpected value 'undefined' imported by the module 'AppRoutingModule in /Users/user/project/src/app/app-routing.module.tns.ts'

这感觉像是 typescript 错误，我不确定。任何帮助将不胜感激。

AppRoutingModule 看起来像这样:
import { NgModule } from "@angular/core";
import { Routes } from "@angular/router";
import { NativeScriptRouterModule } from "@nativescript/angular";
import { ErrorComponent, SecureComponent, PublicComponent } from './components';
import { PUBLIC_ROUTES } from './public.routes';
import { SECURE_ROUTES } from './secure.routes';
import { Guard } from './guard';
const APP_ROUTES: Routes = [
{ path: '', component: PublicComponent, children: PUBLIC_ROUTES},
{ path: '', component: SecureComponent, canActivate: [Guard], children: SECURE_ROUTES},
{
path: '**',
component: ErrorComponent
}
];
@NgModule({
imports: [NativeScriptRouterModule.forRoot(APP_ROUTES)],
exports: [NativeScriptRouterModule]
})
export class AppRoutingModule { }
它被导入到我的主模块中，如下所示:
...
import { AppRoutingModule } from "./app-routing.module.tns";
@NgModule({
bootstrap: [
AppComponent
],
imports: [
NativeScriptModule,
AppRoutingModule,
HttpClientModule,
FormsModule,
ReactiveFormsModule
],
declarations: [
AppComponent,
LoginComponent,
PublicComponent,
SecureComponent,
ErrorComponent,
GeneralComponent,
MainComponent,
MenuComponent,
StoreComponent,
ItemComponent,
HomeComponent,
HashPipe
],
providers: [
AuthService,
AuthRequestService,
StoreRequestService,
OrderRequestService,
StorageService,
Guard,
{
provide: UniversalStorageService,
useValue: mobileStorage
},
{
provide: HTTP_INTERCEPTORS,
useClass: NoopInterceptor,
multi: true
}
],
schemas: [
NO_ERRORS_SCHEMA
]
})
export class AppModule { }
我的文本编辑器突出显示这些行，如下所示，引用 Class NativeScriptRouterModule.forRoot(APP_ROUTES) 不是 Angular 函数。
这对我来说有点阻碍，所以感谢您的帮助。
最佳答案
DepickereSven 在此处引用了升级 Angular 版本所需的更改 https://github.com/NativeScript/nativescript-angular/issues/2238#issuecomment-691459621
删除配置选项
"angularCompilerOptions": {
"enableIvy": false
}
将防止此错误。
此时我应该提到，我首先禁用 Ivy 的原因是为了避免在尝试编译应用程序时遇到不同的 NGCC 错误。
读完这篇文章后https://github.com/angular/angular/issues/37508我发现了确实导致错误的原因。
就我而言，我试图将节点依赖项编译到比某些依赖项允许的更高的目标版本。对于此错误，在 tsconfig.json 中，将目标版本更改为
"compilerOptions": {
"target": "es2017"
...
}
至
"compilerOptions": {
"target": "es5"
...
}
修复了错误。 😊
