angular - 无法绑定(bind)到 'options'，因为它不是 'p-dropdown' 的已知属性

Question

尝试将 primeNG 下拉列表添加到 userform.component.ts 时出现此错误，我已引用此但无济于事，因为我已经实现了此修复:primeng dropdown component error ('p-dropdown' is not a known element)

Uncaught Error: Template parse errors:
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.
2. If 'p-dropdown' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. ("<p-dropdown [ERROR ->][options] = "technologies" [autoWidth] = "false" id = "technologies"></p-dropdown>

通常，当您错过一些导入时会发生此错误。
如果缺少，请添加以下行:

import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { DropdownModule } from 'primeng/primeng';

并将它们添加到导入中。
