我想在我的应用程序中使用这个 PrimeNG-Dropdown。所以我做了什么:
npm i primeng --save
然后我DropdownModule
在我的导入中添加了app.module.ts
. 之后,我在我的 html 中包含了以下代码:
<p-dropdown [options]="optionList" [(ngModel)]="selectionString" placeholder="Choose one"></p-dropdown>
在运行ng serve
和启动localhost:4200
时出现以下错误:
./node_modules/primeng/components/multiselect/multiselect.js 未找到模块:错误:无法解析 '%projectroot%\node_modules\primeng\components\multiselect' 中的 '@angular/cdk/scrolling'
我还尝试从imports
-Array 中删除导入,这导致了不同的错误。我究竟做错了什么?我正在使用 Angular 7 顺便说一句。
删除导入时出现以下错误:
Can't bind to 'options' since it isn't a known property of 'p-dropdown'.
1. If 'p-dropdown' is an Angular component and it has 'options' input, then verify that it is part of this module.

3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. ("
