postgresql - Django on AWS Elastic Beanstalk: Unexpected syncdb error on deploy -

-

i have django/postgresql application. use elastic beanstalk deploy amazon ec2 instance rds.

today, deployment failed following error. older code versions not able deploy. 

[instance: i-f8ae27ce module: awsebautoscalinggroup configset: null] command failed on instance. return code: 1 output: error occurred during build: command 01_syncdb failed .

it's related command in elastic beanstalk config file:

command: "django-admin.py syncdb --noinput"

digging in log files shows above command raises error:

improperlyconfigured("error loading psycopg2 module: %s" % e) django.core.exceptions.improperlyconfigured: error loading psycopg2 module: no module named psycopg2

this weird, because have psycopg2 in requirements.txt, , can verify it's installed. also, have postgresql-devel installed yum package via eb config file.

does know why deployment failed?
