Hi,

If you search on that error from yarn ("yarn error code 137"), you'll find that it means your build process ran out of memory, e.g. https://jcutrer.com/javascript/yarn-build-exit-code-137

You need to make sure your machine ideally has at least 4GB of memory available.  You might be able to build the UI with 2GB, but even that would be pushing it.  We have some DSpace 7 memory recommendations here: https://wiki.lyrasis.org/display/DSDOC7x/Performance+Tuning+DSpace

If you need more help, let us know on this list.
