您需要安装用于构build服务器端扩展的postgresql-server-dev-XY或用于构build客户端应用程序的libpq-dev
我正在使用virtualenv处理Django项目，并将其连接到本地postgres数据库。 当我运行的项目是说，
ImportError: No module named psycopg2.extensions 然后我用这个命令来安装
pip install psycopg2
那么在安装过程中会出现以下错误。

使用下面这些命令，这将解决错误：
sudo apt-get install postgresql
然后开火：
sudo apt-get install python-psycopg2
最后：
sudo apt-get install libpq-dev
我只是从terminal运行这个命令，问题解决了，
sudo apt-get install -y postgis postgresql-9.3-postgis-2.1 pip install psycopg2
要么
sudo apt-get install libpq-dev python-dev pip install psycopg2
对我来说这个简单的命令解决了这个问题
sudo apt-get install postgresql postgresql-contrib libpq-dev python-dev
那我可以这样做：
pip install psycopg2
对于Python 3，我做了：
sudo apt install python3-dev postgresql postgresql-contrib python3-psycopg2 libpq-dev
然后我能够做到：
pip3 install psycopg2
