@description
|
|
Angular can't find a pipe with this name.
|
|
|
|
The [pipe](guide/pipes-overview) referenced in the template has not been named or declared properly.
|
|
|
|
To use the pipe:
|
|
- Ensure the name used in a template matches the name defined in the pipe decorator.
|
|
- Either mark it as standalone by adding the `standalone: true` flag to the pipe's decorator or declare it as a part of an `NgModule` by adding to that module's declarations array.
|
|
- Import it in the standalone components and/or the `NgModules` where it is needed.
|
|
|
|
@debugging
|
|
Use the pipe name to trace where the pipe is declared and used.
|
|
|
|
To resolve this error:
|
|
- If the pipe is local to the `NgModule`, give it a unique name in the pipe's decorator and declared it in the `NgModule`.
|
|
- If the pipe is standalone or is declared in another `NgModule`, add it to the `imports` field of the standalone component or the current `NgModule`.
|
|
|
|
If you recently added an import or declaration, you may need to restart your server to see these changes.
