Angular 9 introduced a global '$localize()' function that needs to be loaded
AngularLocalizationAngular9Angular Problem Overview
I'm getting the following error in my new angular project setup.
Installed Packages and its versions

Note: I came from the following. It suggests falling back to old version. https://github.com/angular/angular/issues/32508
Angular Solutions
Solution 1 - Angular
You need to make sure you have the @angular/localize package first:
npm install @angular/localize --save
Then, import '@angular/localize/init'
in your polyfills.ts file just like the error says
Solution 2 - Angular
The best way if you are using Angular CLI is to run
ng add @angular/localize
It will take care of it automatically
Or else
import '@angular/localize/init';
to your polyfills.ts
Tested with Angular 9
Solution 3 - Angular
If you have many angular projects in same workspace, running
ng add @angular/localize
will add import statement import '@angular/localize/init'
to polyfills.ts in default Project only,i think this will be fixed in later updates.
so you need to add import '@angular/localize/init'
manually to polyfills.ts in other projects.
Solution 4 - Angular
If you are running ng test
and the above answer doesn't work, install the package and add
import "@angular/localize/init"
to polyfills-test.ts
Solution 5 - Angular
Angular 9 introduced a global $localize() function that needs to be loaded if you use i18n.
Run ng add @angular/localize
from the Angular CLI.
Then make sure you have:
@angular/localize
as a dependency in your app's package.jsonimport '@angular/localize/init'
in your polyfills.ts
Solution 6 - Angular
This error started to appear after I upgraded a large Nx/Angular CLI application with multiple sub apps to Angular 10. The solution suggested in the error (Please run ng add @angular/localize
from the Angular CLI) does not work if the application contains multiple apps. Each of these auto-generated app had its own polyfill.ts
. I manually added the import (import '@angular/localize/init';
) in each of the polyfill.ts file. To fix same error while running unit tests, I also had to add the import in test.ts file of libs.
Solution 7 - Angular
As the i18n attributes are now converted to $localize calls in the generated code, we need to load the $localize function.
The CLI offers a schematic to do this for you. Simply run: ng add @angular/localize
It will add the package to your dependencies and the necessary import to your polyfills (import '@angular/localize/init')
You can also refer to the following link for more explanation. https://blog.ninja-squad.com/2019/12/10/angular-localize/
Solution 8 - Angular
The best way to do this is by using Angular CLI:
You just have to run the following command in terminal:
ng add @angular/localize
It will automatically install packages and will also add the import statement in polyfills.ts file.
The import statement is:
import '@angular/localize/init';
If you don't want to go through the CLI approach then you can manually enter the import statement in the polyfills.ts file. Also you have to do one more step is to add the below line in package.json under dependencies tag.
"dependencies":{
...
"@angular/localize":"^9.1.0",
...
}
Solution 9 - Angular
You have to add this package
ng add @angular/localize
then add import '@angular/localize/init';
to your ployfills.ts
But if your tests that are failing in a library, you must add import '@angular/localize/init';
to your test.ts
Solution 10 - Angular
run
npm install @angular/localize --save
Then, in your polyfills.ts
import '@angular/localize/init'
this works for me
Solution 11 - Angular
I changed my operating system because of this problem. And yesterday I found the cause of this problem. I was getting this issue due to a plugin I installed in Visual Studio Code. If you are using Angular9, do not install the first two plugins. You can install the third one.
Solution 12 - Angular
I had this error while updating Angular version from 12 to 13. I followed the instructions:
- Run ng add @angular/localize
- import '@angular/localize/init' in your polyfills.ts
but it did not work for me. I already had @angular/localize in my modules and the import in the polyfills.ts file, after all my Angular 12 app was working fine.
To solve the issue, I had to update the "@ng-bootstrap/ng-bootstrap" version. I hope this suggestion can save some headache to someone, given that there was no apparent link between the outdated @ng-bootstrap/ng-bootstrap version and the error description.
Solution 13 - Angular
For me this error appeared when running npm test
so the solutions above did not help. To solve it I had to import localize in the jest.ts
file.
Just add:
import "@angular/localize/init";
