Question

我正在使用ionic@5.0.0和angular@9.1.0

在一个组件中，突然出现此错误

ERROR in src/app/modules/core/attachmentViewer/attachment-viewer.component.html:1:1 - error NG8001: 'ion-header' is not a known element:
    1. If 'ion-header' is an Angular component, then verify that it is part of this module.
    2. If 'ion-header' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.

    1 <ion-header mode="md">
      ~~~~~~~~~~~~~~~~~~~~~~

      src/app/modules/core/attachmentViewer/attachment-viewer.component.ts:9:16
        9   templateUrl: './attachment-viewer.component.html',
                         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        Error occurs in the template of component AttachmentViewerComponent.

此错误与其他离子性成分重复出现。

我已经在模块中导入了IonicModule。

我已经尝试通过删除node_modules和package-lock.json

来解决此问题。

Ionic5 ion- *不是一个已知的元素
