@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.
|
|
|
|
<code-example format="typescript" language="typescript">
|
|
|
|
import { FormsModule } from '@angular/forms';
|
|
|
|
@NgModule({
|
|
…
|
|
imports: [
|
|
FormsModule,
|
|
…
|
|
|
|
</code-example>
|
|
|
|
If you recently added an import, you will need to restart your server to see these changes.
