我试图在安装了python/django 2.7.6和PostgreSQL 9.3.4的VM上创建一个pythondjango项目。
我正在学习this教程。在Postgres的settings.py中设置changes之后，当我执行vagrant up和vagrant ssh时，在python manage.py syncdb之后，显示以下错误。

django.core.exceptions.improperyconfigured:加载psycopg2模块时出错：没有名为psycopg2的模块
还有一件事，我可以在VM上运行一个带有SQLite的项目。
怎么办？
最佳答案
pyscopg2是通常用于与Postgresql接口的Python模块的名称。你需要安装它。
您应该能够使用Pip和pip install psycopg2安装它。Pip本身通常可以使用您的包管理器找到-例如，在Ubuntu上，IIRC这个包被称为python Pip for python 2和python3pip for python3。
