在角度库中的角度属性指令中注入第三方组件

Question

错误： NullInjectorError： ColumnComponent 没有提供程序！

我创建了一个角度库，然后在库中创建了一个属性指令，主应用程序使用该指令将数据绑定到第三方组件的属性。

src/app/client.component.html

<kendo-grid-column field="id" fcidColumnBinding>
</kendo-grid-column>

这是我在图书馆方面拥有的内容： projects/metadata-lib/src/lib/column-binding-directive.ts

@Directive({
selector: '[fcidColumnBinding]'
})
export class ColumnBindingDirective {
constructor(private metadataLibService: MetadataLibService, private gridColumn: ColumnComponent) { }
public ngOnInit(): void {
//Called after the constructor, initializing input properties, and the first call to ngOnChanges.
//Add 'implements OnInit' to the class.
this.metadataLibService.subscribe((result) => {
this.gridColumn.title = this.metadataLibService.getUIHint(result, this.gridColumn.field, 'DisplayName');
this.gridColumn.width = this.metadataLibService.getUIHint(result, this.gridColumn.field, 'columnWidth');
})
this.rebind();
}
public rebind(): void {
this.metadataLibService.query();
}
}

project/src/lib/metadata-lib.module.ts

import { NgModule } from '@angular/core';
import { MetadataLibComponent } from './metadata-lib.component';
import { MetadataBinidingDirective } from './metadata-biniding.directive';
import { ColumnBindingDirective } from './column-binding.directive';
import { CommonModule } from '@angular/common';
import { DropDownsModule } from '@progress/kendo-angular-dropdowns';
import { GridModule } from '@progress/kendo-angular-grid';
import { ButtonsModule } from '@progress/kendo-angular-buttons';
import { InputsModule } from '@progress/kendo-angular-inputs';
import { ColumnHeaderControlComponent } from './column-header-control/column-header-control.component';
import { ForeignkeyFieldControlComponent } from './foreignkey-field-control/foreignkey-field-control.component';
import { IconFieldControlComponent } from './icon-field-control/icon-field-control.component';
import { ImageFieldControlComponent } from './image-field-control/image-field-control.component';
import { CheckboxFilterControlComponent } from './checkbox-filter-control/checkbox-filter-control.component';
import { DropdownFilterControlComponent } from './dropdown-filter-control/dropdown-filter-control.component';
import { SwitchFilterControlComponent } from './switch-filter-control/switch-filter-control.component';
@NgModule({
imports: [
CommonModule,
DropDownsModule,
GridModule,
ButtonsModule,
InputsModule
],
declarations: [
MetadataLibComponent,
MetadataBinidingDirective,
ColumnBindingDirective,
ColumnHeaderControlComponent,
ForeignkeyFieldControlComponent,
IconFieldControlComponent,
ImageFieldControlComponent,
CheckboxFilterControlComponent,
DropdownFilterControlComponent,
SwitchFilterControlComponent,
],
exports: [
MetadataLibComponent,
MetadataBinidingDirective,
ColumnBindingDirective,
ColumnHeaderControlComponent,
ForeignkeyFieldControlComponent,
IconFieldControlComponent,
ImageFieldControlComponent,
CheckboxFilterControlComponent,
DropdownFilterControlComponent,
SwitchFilterControlComponent,
]
})
export class MetadataLibModule { }

我想知道我们可以在角度库指令中使用 3rd 方组件吗？

Answer 1

最后我想，是的，我们可以。 我花了很长时间才正确配置它。

所以答案是肯定的。如何？

库模块.ts非常关键，你需要在import：[]中导入第三方模块，当你使用它时，你不应该相信Visual Studio代码建议路径。 您需要手动设置它 是什么破坏了我的代码 这

import { ColumnComponent } from '@progress/kendo-angular-grid';

这是

import { ColumnComponent } from '@progress/kendo-angular-excel-export';

所以总结一下： 1，是的，我们可以使用第三方，也可以在角度库中使用绑定指令AKA属性指令。我还不确定管道。我无法解决角度库内管道的问题。 2. 在开发 Angular 库时不要信任 IDE 的建议路径，
