When I typed python build-spark-local.py, it shows the following errors, what should I do?

Traceback (most recent call last):

Hi @RuihanZhang2015,
I've had the same error. I think it's caused by a missing prerequisite: maven.
I installed it with sudo apt-get install maven and the building worked fine.

Best,
Tong
