We solve this problem (when compile with ng build -c mhsb) we use following command.

.\ngs.cmd build -c mhsb

ngs.cmd: @node --max_old_space_size=8192 node_modules/@angular/cli/bin/ng %1 %2 %3 %4 %5

When we use this command, when the compile process reaches 92% after 10 minutes, it encounters the error below.

@alialtun14 are you seeing this with version 9 now, and did it not happen with version 8?

I'd like to take a look at the project if possible. Giving me access to a new private github repository is a good way of doing this for private projects.

[alialtun14]

We have taken same error when we used "ng build -c mhsb". We have solved this problen i V8 by using max_old_space_size=8192. Today after upgrading to V9 and compile with max_old_space_size=8192 we started the error again.

Our project is in gitlab reposiyory. If you share your email adrese with alialtun14@gmail.com. I can share zip file of our project.

Hi - error in private company repo: What could You help:

• newest cli, and all ng.
• when targeting es5 all works fine,
• when target is es2015 , build ends with stackoverflow :/
• optimalization false helps but this is not a solution :/

ps. dont suggest by dir nam - it is ng9 ;) 

[filipesilva]

@4zriel I edited your comment to remove a large chunk of terser warnings in the log that I reviewed and know is not relevant to the problem at hand. I removed it because it was very long and made it hard to read the rest of this issue thread.

[filipesilva]

@alialtun14 I just tried building with the increased memory and it seemed to build fine:

What version of node are you on? There were a couple of node versions that had memory problems. I am on Node v12.4.0.

@4zriel what version of node are you on as well? Can you try the one I mentioned above, or perhaps considering sharing the project privately with me?

[4zriel]

@filipesilva I'll love to share but then I'll propalby need to look for another work ;) I'm using node 13.3.0, and I tried 1st this trick with inceased memory (I set sth about 10k maybe it is too much...) but it didn't change anything...As i said - ng serve and ng buil (without --prod so without --optimization works perfectly fine). It is quite big monorepo, with a lot of iternal lib, but ng update worked surpriselgly well :)

[filipesilva]

@4zriel since you have a monorepo, I think you might be suffering from case 2 in https://angular.io/guide/ivy-compatibility#payload-size-debugging. Can you try the approach described in #16799 (comment) and see if it works please?

To be clear, the approach is to add "sideEffects": false to the package.json of shared libraries. If the library doesn't actually have a package.json, you can add one with just {"sideEffects": false}.

[4zriel]

@filipesilva That's it! :D You are awasome! I spend like 2h at least on this, read through the docs and other issuess but all I need was just 'sideEffects: false'! :D

[filipesilva]

Glad to hear it helped!

[alialtun14]

@filipesilva

We transferred the project to Angular 9. Thank you for your interest and help.

We can now build with enableIvy: false. When we make Enable Ivy: true and compile, we get errors. We are now in the process of eliminating those errors.

What version of node are you on? There were a couple of node versions that had memory problems. I am on Node v12.4.0.

We started using node v12.15.0 with Angular 9.

After node v12.15.0, we can compile "node node_modules/@angular/cli/bin/ng build -c mhsb" without any memory problems.

Thank you for your interest and help.

[filipesilva]

@alialtun14 oh wow that's a great improvement, glad to hear!

[filipesilva]

Btw @alialtun14 I noticed you have a vendor chunk, we recommend turning it off in production because it causes increases in total size. You can turn it off in your production configuration with "vendorChunk": false.

[alialtun14]

"vendorChunk": false

@filipesilva According to the blog post by @StephenFluin, bundle size in large app can reduce maximum %40 with ivy compile. In our project we reached to %68 in size and % 72 in time reduction. Is this an expected result or are we making a mistake somewhere :) This result was a great and pleasing surprise for us.

without Ivy	with Ivy	Reduce (%)
11,6 MB	3,72	68
1248877 MB	344095	72

[filipesilva]

If your app is working properly, I don't think you've done anything wrong. Your project might be a new record for size savings with Ivy :D

[alialtun14]

If your app is working properly, I don't think you've done anything wrong. Your project might be a new record for size savings with Ivy :D

We started using in production after compiled. There were a few problems we encountered during the compilation. We fixed the problems with your support.

[KurtGokhan]

@filipesilva I am not sure if it is related to this issue but:

I am getting this error in CircleCI. But it builds perfectly in local or Heroku. CLI version: 9.0.2

ERROR in main.5e6bd3ca7eb1cdef2086.js from Terser

Disabling optimization works but it is not desirable.

Things I tried and did not work:

• Using --max_old_space_size=4096 / 8192
• Node versions: 10.x, 12.x, 13.x
• Disabling source maps
• Disabling differential loading. I got the same error but the place where I got the error changed.

I see that terser has a problem with CircleCI and it is recommended to use parallel option. But I don't know how to do that in Angular. Related links:

https://github.com/webpack-contrib/terser-webpack-plugin#parallel https://github.com/webpack-contrib/terser-webpack-plugin/issues/202#issuecomment-580704210

[filipesilva]

@KurtGokhan we use the parallel option but let terser-webpack-plugin figure out the real count, and this seems to be a problem in CircleCI. Maybe we should limit the maximum to get around this problem...

[filipesilva]

@KurtGokhan https://github.com/angular/angular-cli/pull/16978 should help with that problem.

[KurtGokhan]

@filipesilva I tested a build from your branch and it works while the master branch build fails. Thank you.

Meanwhile I switched to Github Actions and it works correctly as well.

[Zwartpet]

@filipesilva I'm running into the same problem

[Zwartpet]

I think it would help if I can limit the number fixed in https://github.com/angular/angular-cli/pull/16978 as 7 is still to much for a container

[gnomeontherun]

Agreed, @filipesilva it would be great if we can configure the parallel value ourselves since Circle still fails out with max retries after your fix was installed.

@Zwartpet I think the error you are seeing is not the same as the one mentioned above. That is because downlevelling happens after running the Webpack build.

This issue is mostly caused by JestWorker usage in https://github.com/angular/angular-cli/blob/master/packages/angular_devkit/build_angular/src/utils/action-executor.ts. JestWorker uses the following logic to determine the number of workers to spawn https://github.com/facebook/jest/blob/fa8ef2269ceb52ee1bec2e77ba4358dd4ade85b2/packages/jest-worker/src/index.ts#L80

@alan-agius4 But why not make it configurable? I doubt that this will resolve the issue as it still spawns more workers then I there is room for in a container.

But let me test it before i make an assumption

@filipesilva CircleCI build is working with the new patch.

Apart from that, builds take longer time on CI with Ivy. Because ngcc compiler runs every time. Is there a way to cache ngcc compiling result? Which folders should be cached?

What I mean is this part:

Compiling @angular/core : es2015 as esm2015

Compiling @angular/common : es2015 as esm2015

Compiling @angular/platform-browser : es2015 as esm2015
...

[Zwartpet]

Everything is compiled into the node_modules directory, so that should be cached.

There’s a npm/yarn postinstall command you can use (and tweak) on: https://angular.io/guide/ivy

I was using npm ci, which deleted node_modules. Switched to npm i and workflow got a lot faster.

@dgp1130 in #17027 you said:

If you're still seeing memory issues after that is merged and released, then we can reevaluate.

I use last version of angular-cli and still have erros like in this comment (https://github.com/Automattic/wp-calypso/pull/39535#issuecomment-589603920): Error: Call retries were exceeded and Error: write EPIPE.

Could you add option to configure parallel in terser?

[petebacondarwin]

@nac0n - I believe that your issue is because there is a circular dependency within the source-map - source tree, which ngcc is not handling well. Tracking at FW-2041. The description in that issue is:

In the ngcc-validation project we have noted that angular-draggable-droppable causes ngcc to crash with a stack-overflow when processing the UMD format!

This is because the source-map for this file contains inline source content that is has a source-map comment that references the original source-code. There is already cycle detection in the source-map loading algorithm but it only covers case where the source file is loaded more than one, creating a cycle. In this case the source is not loaded from a path on disk but is internal to the source-map itself, so it is not being caught and an infinite recursion is happening.

The proposed solution is to track the paths to the source-map files in addition to the paths to the source files.

I'll see if we can bump it up the priority queue.

[nac0n]

@petebacondarwin - I see, we'll have the postinstall script and other occurrences with angular-draggable-droppable disabled for the time being if we can and will keep ourselves updated looking for fixes to it then. Thanks for the response.

Edit: I do not have access to that issue tracking, just a note. However, i trust that the information about the bugfix will reach consumers.

[petebacondarwin]

@nac0n - The fix to be more resilient to cycles in source-maps was landed in 9.1.1 - https://github.com/angular/angular/pull/36452

[faisalzamankhan]

i am installing angular material and getting error and I think this is due to angular cli version 9

[LastDragon-ru]

Initial ng build ("Compiling ... es2015 as esm2015") requires 4GB of ram for a fresh empty app with angular material (all latest). Is this really normal? :|

[nac0n]

@nac0n - The fix to be more resilient to cycles in source-maps was landed in 9.1.1 - angular/angular#36452

Thanks for the help @petebacondarwin, looks like it doesn't crash anymore and the ngcc compilation goes through. But, we also get errors when running ngcc compilation.

node_modules/@angular/common/common.d.ts:115:22 - error NG6002: Appears in the NgModule.imports of MatTabsModule, but could not be resolved to an NgModule class.

This likely means that the library (@angular/common) which declares CommonModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

115 export declare class CommonModule {

MatTabsModuleis not the only one that appears as an error, there's also MatSelectModule, MatStepperModule, MatSliderModule, MatSidenavModuleand so on...

This error however doesn't appear again after the ngcc is done. We're running ng build and ng serve and we get a successful build/serve. I suppose this works even without the postinstall being successful...?

[petebacondarwin]

We think that this might be caused by the fact that some library (like @angular/cdk/coercion) is not an Angular entry-point but is depending upon @angular/common - and ngcc is not checking its dependencies. This causes ngcc to get the order of processing wrong and allows the filesystem cache of the @angular/common typings file to be populated before it is processed. @JoostK is working on it...

[JoostK]

The @angular/cdk/coercion entry-point depends on @angular/core, not @angular/common. So I'm afraid it has a different cause. @nac0n it would be helpful if you could share additional logging or a reproduction, including the workflow that you use. E.g. is ngcc run only from the CLI or as a postinstall script?

[nac0n]

@JoostK We run ngcc via postinstall. So ngcc is running when npm install has been ran. No other arguments, only "postinstall": ngcc

This likely means that the library (@angular/common) which declares CommonModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if 
a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Iv
y.

@nac0n Thanks, that is very helpful. It does indeed look like the issue that Pete mentioned, but as @angular/common is affected and not @angular/core it is not caused by @angular/cdk/coercion (I checked and there is no import of @angular/common there).

Could you share your package.json so that I can try running ngcc myself? Just the package.json should be enough to just kick off ngcc. If there's any private dependencies feel free to remove them, hopefully I can reproduce without those being present)

[petebacondarwin]

@nac0n - could you provide us with a reproduction that we could play with?

@nac0n Thanks, it fails for me too! This should allow us to establish the root cause and work towards a fix.

We have a problem with our jenkins build since we migrated to Angular 9. Everything works fine on our local machines, but when we run the build job on jenkins it fails. npm and node versions are the same on all machines. The error appears only with "ng build --prod" - "ng build" works on jenkins.

Today I updated to Angular Cli 9.1.3 - my problem (one comment above) is still there.
