I am trying to build my angular application using 'ng build'. It is failing because it is running out of memory to build as I surmise from my research. I have tried several of the solutions out there with no luck. After typing 'ng build' either from VSC terminal or on DOS line, it runs for about 3 minutes during this step:
Generating ES5 bundles for differential loading...
then it fails with this error written to my angular-errors.log file:
[error] Error: Call retries were exceeded
    at ChildProcessWorker.initialize (c:\development\gems\Frontend_Serenity_A9_SLIM\Frontend_Serenity_A9\node_modules\jest-worker\build\workers\ChildProcessWorker.js:193:21)
    at ChildProcessWorker.onExit (c:\development\gems\Frontend_Serenity_A9_SLIM\Frontend_Serenity_A9\node_modules\jest-worker\build\workers\ChildProcessWorker.js:263:12)
    at ChildProcess.emit (events.js:203:13)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:272:12)
I have tried increasing my memory as some articles/stack overflows have indicated. I tried this:
npm install -g increase-memory-limit
and then ran this command at the root of my angular project:
increase-memory-limit
to no avail. Using es5 rather than es2015 is not a solution for our app. Any help or ideas you can offer are GREATLY appreciated. I have been trying everything for a week now and am still stuck. Thanks!
