我正在Amazon EC2服务器上安装python 3.5，django 1.10和psycopg2 2.7.1，以便使用Postgresql数据库。我在虚拟环境中使用python 3，并遵循经典的安装步骤：

cd /home/mycode
virtualenv-3.5 p3env
source p3env/bin/activate
pip install django
cd kenbot
django-admin startproject kenbot
pip install psycopg2

然后，我在项目中编辑了settings.py文件，以定义DATABASE设置：

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.postgresql_psycopg2',
    'NAME': 'deleted',
    'USER': 'deleted',
    'PASSWORD': 'deleted',
    'HOST': 'deleted',
    'PORT': '5432',
}   

最后，我键入（仍然在虚拟环境中）：

python manage.py makemigrations

并得到以下错误：

Traceback (most recent call last):
  File "/home/mycode/p3env/local/lib/python3.5/dist-packages/django/db/backends/postgresql/base.py", line 20, in <module>
    import psycopg2 as Database
ImportError: No module named 'psycopg2'

During handling of the above exception, another exception occurred:
