我正在尝试升级我的nativescript应用程序以使用新的Angular Router,但是,我收到以下错误消息:
java.lang.RuntimeException: Unable to create application com.tns.NativeScriptApplication: com.tns.NativeScriptException: Failed to find module: "@angular/router/common_router_providers", relative to: /app/tns_modules/

在我的main.ts
我有:
import {nativeScriptBootstrap} from "nativescript-angular/application";
import {AppComponent} from "./app.component";
import {APP_ROUTER_PROVIDERS} from "./app.routes";
nativeScriptBootstrap(AppComponent, [APP_ROUTER_PROVIDERS]);
然后在我的app.routes.ts
我有:
import {RouterConfig} from '@angular/router';
import {nsProvideRouter} from "nativescript-angular/router";
import {HomePage} from "./Components/Home/home.component";
import {Bottles} from "./Components/BottleList/bottleList.component";
const routes: RouterConfig = [
{ path: "", redirectTo: "/home", terminal: true },
{ path: "home", component: HomePage },
{ path: "bottles", component: Bottles },
];
export const APP_ROUTER_PROVIDERS = [
nsProvideRouter(routes, {enableTracing: false })
];
然后我的app.component.ts
:
import {Component, OnInit} from "@angular/core";
import {NS_ROUTER_DIRECTIVES} from "nativescript-angular/router";
@Component({
selector: "main",
directives: [NS_ROUTER_DIRECTIVES],
template: "<page-router-outlet></page-router-outlet>"
})
export class AppComponent implements OnInit {
page: Page;
}
任何想法我做错了什么?

我找到了一些东西,但它只是一种解决方法:使用angular2组件的所有rc3版本(路由器(3.0.0-alpha.7除外)和路由器弃用(2.0.0-rc.2除外) )), 有用。但您也需要在文件中添加一些更改(请查看here)
答案 1 :(得分:1)
我上周从@angular/router": "3.0.0-alpha.7
升级到@angular/router-deprecated": "2.0.0-rc.2
并成功升级。
看看这个 NativeScript / sample-Groceries 分支https://github.com/NativeScript/sample-Groceries/tree/angular-v3-router它有rc3升级提交。
同时删除平台&amp;全局 tns_modules 文件夹和升级(删除并安装) tns 可能会解决您的问题。

具有完全相同的行为。目前唯一的解决方法似乎是将.ToDictionary(
item => item,
item => (IReadOnlyCollection<T>) relatedItemsSelector(item)
.ToList()
.AsReadOnly() // Didn't expect to need the direct cast
)
留在版本3.0.0-alpha.7
