How can I sync two amazon buckets using the AWS CLI?

Question

I'm using the AWS S3 CLI to sync two buckets, following the Amazon CLI S3 SYNC format specified in the documentation, as follows:

aws s3 sync s3://source_bucket s3://target_bucket --exclude *.tmp

But I get the following error:

A region must be specified --region or specifying the region in a configuration file or as an environment variable. Alternately, an endpoint can be specified with --endpoint-url

I have scoured the internet in addition to AWS CLI docs and find no reference to --region in the context of S3 SYNC. Any guidance would be appreciated!

Probably immaterial, but I am running Mac OS X Mavericks 10.9.1 on an MBPr (16GB RAM, 512GB SSD, quad-core)

You can set the AWS_DEFAULT_REGION environment variable.

export AWS_DEFAULT_REGION="us-east-1"
