Previously, some of the links on the error pages had URLs prefixed with `https://angular.io/`. This caused them to be treated as external URLs, which had the following downsides: - Links would always point to `angular.io` instead of the same version as the error page (e.g. `next.angular.io` or `v11.angular.io`). - Dgeni would not be able to check that the URLs are valid (i.e. point to existing pages). - An external link icon would incorrectly be shown next to the links on `angular.io`. This commit fixes the links to use relative URLs. PR Close #40881

@shortDescription No directive found with export
|
||
|
||
@description
|
||
Angular can’t find a directive with `{{ PLACEHOLDER }}` export name. This is common with a missing import or a missing [`exportAs`](api/core/Directive#exportAs) on a directive.
|
||
|
||
|
||
<div class="alert is-helpful">
|
||
|
||
This is the compiler equivalent of a common runtime error [NG0301: Export Not Found](errors/NG0301).
|
||
|
||
</div>

|
||
Use the string name of the export not found to trace the templates or modules using this export.
|
||
|
||
Ensure that all dependencies are properly imported and declared in our Modules. For example, if the export not found is `ngForm`, we will need to import `FormsModule` and declare it in our list of imports in `*.module.ts` to resolve the missing export error.
|
||
|
||
```typescript
|
||
import { FormsModule } from '@angular/forms';
|
||
|
||
@NgModule({
|
||
...
|
||
imports: [
|
||
FormsModule,
|
||
…
|
||
```
|
||
|
||
If you recently added an import, you will need to restart your server to see these changes.
