AWS EC2의 서버 코드와 RDS의 Spatial DB Postgis로 애플리케이션을 구축하려고합니다. 나는 명령 행 사용하여 EC2에서 포스트 그레스에 액세스 할 수 있습니다 내가 EC2에 GeoDjango를 사용장고 AWS EC2, Postgres Postgis on RDS
psql --host=mydbpostgres.qazwsxedcrfv.us-west-1.rds.amazonaws.com --port=5432 --username=ec2 --password --dbname=mydb
mydb=>
, 이것은 내 DB에 대한 설정입니다 :
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'mydb',
'USER': 'ec2',
'PASSWORD': 'password',
'HOST': 'mydbpostgres.qazwsxedcrfv.us-west-1.rds.amazonaws.com',
'PORT': '5432',
}
}
하지만 마이그레이션을 실행할 때, 내를 제공합니다 다음과 같은 오류가 발생했습니다 :

내 EC2에서 일부 포스트 그리피스 라이브러리가 누락 된 것 같습니다. 내 질문은, 내 서버가 필요한 모든 libs 찾을 수 있도록 ec2에 postgis 인스턴스를 설치해야합니까? 아니면 RDS에서 libs를 찾도록 서버를 만들 수 있습니까?
대단히 감사합니다.
