错误消息

Question

我正在尝试对我的项目使用ng-block-ui依赖项。问题是它在Angular 7上无法正常工作。我已经在Angular 6项目中使用了它，并且工作正常

app.module.ts

import { BlockUIModule } from 'ng-block-ui';


@NgModule({
     BlockUIModule.forRoot()
})

component.ts

import { BlockUI, NgBlockUI } from 'ng-block-ui';

export class *classname* implements OnInit {
     @BlockUI('departure') blockUIList: NgBlockUI;

     constructor() { this.blockUIList.start('Loading Page...'); }
}

component.html

<div class="kt-portlet kt-portlet--mobile" *blockUI="'departure'">

错误消息

我对此有疑问。

从ng-block-ui中的fesm5 / ng-block-ui.js中更改isActive = true时，我出错了。

这不是一个完美的解决方案，ng-block-ui.js->行：114 [this.blockUIInstances [name] .isActive = isActive] ==> this.blockUIInstances [name] = Object.assign（{}，这。 blockUIInstances [name]，{isActive：isActive}），则可以修复它而不会出错。

（Angular 7）无法在ng-block-ui上分配为只读属性'isActive'
