Makemigrations não funciona por causa Psycopg2

Ao tentar executar, aparece erro ( raise ImproperlyConfigured("Error loading psycopg2 module: %s" % e) django.core.exceptions.ImproperlyConfigured: Error loading psycopg2 module: DLL load failed while importing _psycopg: Não foi possível encontrar o módulo especificado.)

(venv) PS C:\aplicacao> python manage.py makemigrations Traceback (most recent call last): File "C:\aplicacao\venv\lib\site-packages\django\db\backends\postgresql\base.py", line 25, in import psycopg2 as Database File "C:\aplicacao\venv\lib\site-packages\psycopg2_init__.py", line 51, in from psycopg2.psycopg import ( # noqa ImportError: DLL load failed while importing _psycopg: Não foi possível encontrar o módulo especificado.

During handling of the above exception, another exception occurred:

Boa tarde, pergunto se a biblioteca psycopg2 está instalada (pip install psycopg2). A versão desta biblioteca deve ser compatível com a versão do PostgreSQL instalado.
