[英]Webpack WARNING in ./node_modules/express/lib/view.js Critical dependency: the request of a dependency is an expression
[英]Critical dependency: the request of a dependency is an expression (Angular CLI Warning)
在這里,我試圖在惰性路由模塊中動態加載惰性子路由。
例如:
const serverResponse = [
{
path: "transaction",
children: [
{
path: "finance",
modulePath: "./modules/finance/finance.module",
moduleName: "FinanceModule",
},
],
},
];
const routes: Routes = [];
@NgModule({
imports: [RouterModule.forChild(routes)],
exports: [RouterModule],
})
export class LoanOriginationRoutingModule {
constructor(private router: Router) {
this.router.events.pipe(take(1)).subscribe((event) => {
const parentRoute: any = this.router.config.find(
(route: any) => route.path === "loanoriginationLib/loanorigination"
);
serverResponse.forEach((item) => {
const childRoutes = item.children.map((subItem) => {
return {
path: subItem.path,
loadChildren: () =>
import(subItem.modulePath).then((m) => m[subItem.moduleName]),
};
});
parentRoute._loadedConfig.routes.push({
path: item.path,
children: childRoutes,
});
});
this.router.resetConfig(this.router.config);
});
}
}
然后,我將在控制台中收到以下警告:
Critical dependency: the request of a dependency is an expression
此外,當我嘗試通過應用程序訪問財務模塊時,我會在瀏覽器控制台中收到以下錯誤:

有什么辦法可以做到這一點?
感謝您的時間和考慮。
路由需要在編譯器和捆綁程序的構建期間進行靜態分析,因此我得到Critical dependency: the request of a dependency is an expression
警告,當在瀏覽器中瀏覽應用程序時出現Error: Cannot find module './modules/finance/finance.module' Error: Cannot find module './modules/finance/finance.module'
,因為它在捆綁應用程序的上下文中不存在。
所以現在我可以做的就是靜態聲明路由。
