Hi Jaya,

I googled that error, and it seems that a "exit code 137" from yarn means that 
you ran out of memory (and/or swap space).  See for example: 
https://jcutrer.com/javascript/yarn-build-exit-code-137

I think​ you are going to need at least 2GB of memory to build the app.  If 
somehow that doesn't work, you could try 3 or 4, but I think 2GB should be 
enough.

You should also verify you are running Node v12 or v14 (which is what we 
recommend for the UI). Older versions of Node (like v10 or below) might work, 
but they don't do a good job of managing memory...so you are much more likely 
to hit memory issues.

Tim

Dear Euler,
I have done the setting and run again the YARN START.

Hi Jaya,

Did you create a file named environment.prod.ts in your 
[dspace-angular]/src/environments/ directory?

Please see step number 4 in the Frontend installation portion.

Create a Production Configuration file at 
[dspace-angular]/src/environments/environment.prod.ts. You may wish to use the 
environment.template.ts as a starting point. This environment.prod.ts file can 
be used to override any of the default configurations specified in the 
environment.common.ts (in that same directory).  At a minimum this file MUST 
include the "ui" and "rest" sections similar to the following (keep in mind, 
you only need to include settings that you need to modify)

Regards,
euler
