我正在尝试构建我的项目,当我在ng serve
本地运行时,该项目正常运行。
但在ng b -prod
我得到:
ERROR in app\logged-in\content\routing\routing.component.ts(9,16): Error during template compile of 'RoutingComponent'
[ERROR] Function expressions are not supported in decorators in 'slideLeft'
[ERROR] 'slideLeft' references 'ɵ0'
[ERROR] 'ɵ0' contains the error at assets\animations\router.animations.ts(2,15)
[ERROR] Consider changing the function expression into an exported function.
这里是正在加载的文件:
import {sequence, trigger, animate, style, group, query as q, transition, animateChild} from '@angular/animations';
const query = (s,a,o={optional:true})=>q(s,a,o);
export const slideLeft = trigger('slideLeft', [
transition('* => *', [
query(':enter, :leave', style({ position: 'fixed', width:'100%' })),
query(':enter', style({ transform: 'translateX(100%)' })),
sequence([
query(':leave', animateChild()),
group([
query(':leave', [
style({ transform: 'translateX(0%)' }),
animate('1s cubic-bezier(.86,.01,.27,1)',
style({ transform: 'translateX(-100%)' }))
]),
query(':enter', [
style({ transform: 'translateX(100%)' }),
animate('1s cubic-bezier(.86,.01,.27,1)',
style({ transform: 'translateX(0%)' })),
]),
]),
query(':enter', animateChild()),
])
])
]);
以及加载它的组件:
import {Component, OnInit} from '@angular/core';
import {slideLeft} from '../../../../assets/animations/router.animations';
import {Router} from '@angular/router';
@Component({
selector: 'app-routing',
templateUrl: './routing.component.html',
styleUrls: ['./routing.component.scss'],
animations: [slideLeft]
})
export class RoutingComponent implements OnInit {
router:Router;
constructor() {}
ngOnInit() {}
getState(outlet) {
return outlet.activatedRouteData.state;
}
}
这里有什么问题?
我发现了这个问题:https://github.com/angular/angular/issues/10789这是我遇到的问题吗?

问题来自你的lambda函数,如错误中所述。
您可以逐个更改查询,使其成为可选项,而不是使用lambda函数执行此操作:

AOT编译非常重要,因为它可以显着减小应用程序的大小并大大提高性能。
