@Aabhusan looks like a node out of memory error. What are the resources of the machine you're trying to build this on?

[Aabhusan]

@nytai , i ma using t2.micro ec2 instance should i upgrade the instance type??

[nytai]

@Aabhusan that would be my first try, you'll want something with ~8gb of memory for the build. Alternatively you could try changing some of the flags on this line https://github.com/apache/incubator-superset/blob/master/superset/assets/package.json#L17

NODE_OPTIONS=--max_old_space_size=8192 tells node how much memory it has available
