Por alguna razón, al hacer unagrunt build en mi máquina virtual, simplemente se apaga de esta manera:

...
Running "concurrent:dist" (concurrent) task
Killed

No estoy seguro de lo que está pasando. Parece poder construir en mi computadora local, no estoy seguro de por qué no funciona en mi VM.

¿Algunas ideas? ¡Gracias!

ACTUALIZAR

grunt build --verbose

Running "concurrent:dist" (concurrent) task
Verifying property concurrent.dist exists in config...OK
Files: [no src] -> dist
Killed
