Issue

Upgrading to the latest version (7) I am not able to build my project locally (Linux, ubuntu 64bits, 32gb RAM) nor... on CI 😿

Mention any other details that might be useful

Seems that the culprit might be Terser... Eventually that might be related to #12646 but I'm not sure

Also, the compilation is fine without the --prod

[alan-agius4]

I think the difference between v6 and v7 is the bug reported in #12646 as in that issue production builds are taking longer, which usually indicated that more code is being processed and more memory is needed.

The general issue for running out of memory is #5618. As projects grow bigger, they use more memory, and might need to increase the default memory limit. There's more information on this in #5618 (comment).

In your case the only thing you did was to update from v6 to v7 and it should not need significantly more memory than before. I'll look at that problem in #12646.

This has been changed in angular 7 now. I couldn't able to find the path of ng.. Please any help for finding its path in node modules..

ng build --configuration=production

[kumaraditya1999]

I am facing the same issue, I migrated my project from Angular 4 to Angular 8 . The ng serve workss fine but ng serve --prod shows the same problem. I have used the increase-memory-limit but I face the same problem. Any other suggestion of what to do ?

Same problem here, with Angular 8:
