Call retries were exceeded exception while ng build

Question

I am facing an exception while ng build (generating ES5 bundles for differential loading...)

An unhandled exception occured: Call retires were exceeded

Used versions:

Angular-CLI: 8.3.20
Angular: 8.2.7
Node: 12.12.1

Also in logs, it is mentioned

[error] Error: Call retries were exceeded at ChildProcessWorker.initialize

In tsconfig.app.json if you have `target: es2015` change it with `target: es5` — TintinSansYeux, Dec 30 '19 at 13:08
@Angular Can you please tell, why es2015 was causing this exception? — Savan Gadhiya, Dec 31 '19 at 10:56
@TintinSansYeux if we want to use the differential loading we must set the target to es2015 — hosein, Jul 13 '20 at 07:17
This worked for me. I just deleted `node_modules/` and reinstalled. — Schmorrison, Apr 05 '20 at 17:25
its really work just remove node_modules and install again, its working fine — vishal sharma, Jun 25 '20 at 17:01

Update 10.02.2019

This was a problem of the @angular/cli. Updating the version to >= 8.3.22 should fix the issue: see this comment in #16515

ORIGINAL

Basically the build process is running out of memory: see related angular-cli issues #15493, #16515

The recommended remedy is to:

update node to the latest version e.g. 12.14.0
increase the memory for the build process:
- in your package.json change the "build" script to: node --max_old_space_size=4096 node_modules/@angular/cli/bin/ng build
- in this case the memory is increased to 4GB
  depending on the size of your project you may need more

As a quick workaround it could also work to use older versions of angular/cli and build-angular:

"devDependencies": {
    "@angular-devkit/build-angular": "0.803.20",
    "@angular/cli": "8.3.20",

Another workaround is to disable differential-loading (i.e. skip generation of ES5 bundles), if you want this. Then the build-process will need less memory and may work.

`node --max_old_space_size=4096` did not worked for me. With 8GB it worked. – Jonas Marty Jan 07 '20 at 08:21
I was facing the same issue and it is fixed with above commad - node --max_old_space_size=4096 node_modules/@angular/cli/bin/ng build – purnima kamble Feb 11 '20 at 11:48
only disabling `differential loading` worked for me :( – Obay Abd-Algader Jul 06 '20 at 19:18
I have Angular CLI: 9.1.12 and this is happening to me also. I'm building an ionic app. @TmTron, what would you suggest in this case? – D.Hodges Sep 28 '20 at 15:58

@D.Hodges I suggest you post a new question and add the ionic tag. – TmTron Sep 28 '20 at 16:28
It can help if you remove compatibility with older browsers https://angular.io/guide/deployment#differential-loading – nelson6e65 Oct 03 '20 at 16:18
changed to 2048 on my AWS instance with 2GB RAM – works! – Serhii Topolnytskyi Oct 26 '20 at 11:15
It has something to do with building the app with "es2015". Using the old target "es5" worked on my side – Zdravko Kolev May 18 '21 at 06:33

For me editing tsconfig.json resolved my problem.

There was a change in @angular-devkit/build-angular which updated the differential loading. To fix this in your Ionic project, change the target value from “es2015” to “es5” in your tsconfig.json

Thank you Aravindh, this resolved my problem as well. – Arshad Jul 27 '20 at 07:56

But I need es2015, because es5 fails for @angular/fire 6.0.3 and other. https://github.com/angular/angularfire/issues/2521 – nelson6e65 Oct 03 '20 at 15:54

This is not a "solution", just a hack/patch that will have other negative side effects – Richard Apr 28 '21 at 13:45

Use

node --max_old_space_size=6144 ./node_modules/@angular/cli/bin/ng build

This works like I charm. For any other beginner like me out there, you replace your build command in package.json with this. – Suyog May 24 '21 at 06:05

I have also met the same issue, by changing the angular/cli version to 8.3.19, the issue has been resolved.

The proposed workarounds above did work for me but there is now a much more elegant solution, tested for Angular9 and above.

No need to mess around manually with the JS heap allocation anymore (node --max_old_space_size=4096...), which most of us are not comfortable with.

The solution is just to add "sideEffects": false to your package.json file.

I found this awesome solution on the official Angular GitHub issues page here and it works smoothly for me.

I ran into a similar issue a few days ago.

I was using Node v10 and could only avoid the exceptions during production build by changing to "target": "es5" in tsconfig.json. This removed differential loading, which was undesireable.

However, after updating to Node v14, I no longer get the exceptions and am able to use "target": "es2015" again.

This only applicable for those who have migrated their app to angular 10 and increasing memory also not helping

check your "typescript" and "@types/node" in package.json check whether they are compatible or not in https://www.npmjs.com/package/@types/node

try to downgrade @angular-devkit/build-angular below 0.8XX.X
