Setup error on fresh install

[tango]

Hi,

I am trying to install 1.9.x on a fresh ec2 in AWS. Database is Redis configured as a cluster. 0001-001 has an ip address of 10.0.0.31 The read replica 0001-002 has an ip address of 10.0.0.78

When I run setup on one of the ec2 instances I get errors

2018-05-29T04:48:02.122Z [3269] - warn: [cache-buster] could not read cache buster Error: ENOENT: no such file or directory, open '/home/ec2-user/nodebb/build/cache-buster'

Any idea where I might be going wrong?

Thanks in advance

I noticed a recommendation of running ./nodebb build which performed successfully. I then attempted to run setup again & now get error message
