我想将 PostgreSQl 与 Django 一起使用。我参考了本教程来安装它，当我运行这个命令时

python manage.py syncdb

我收到以下错误

Traceback (most recent call last):

    import psycopg2.extensions
ImportError: No module named psycopg2.extensions

我也看到了这个问题并执行了这个

sudo apt-get build-dep python-psycopg2
pip install psycopg2

但是这样做后我仍然遇到同样的错误

使用sudo确保正在安装所有软件包；否则，安装可能会失败，您可能不会注意到指示失败是权限问题导致的错误消息。
