您需要安装postgresql-server-dev-X。Y用于构建服务器端扩展，或者libpq-dev用于构建客户端应用程序

我正在使用virtualenv进行Django项目，并将其连接到本地postgres数据库。当我运行这个项目的时候，

ImportError: No module named psycopg2.extensions

然后我使用这个命令来安装

pip install psycopg2

然后在安装期间，它给出以下错误。

我只是在终端上以根用户的身份运行这个命令，问题就解决了，

sudo apt-get install -y postgis postgresql-9.3-postgis-2.1
pip install psycopg2

sudo apt-get install libpq-dev python-dev
pip install psycopg2

只需安装libpq-dev

$ sudo apt-get install libpq-dev

对我来说，这个简单的命令解决了问题:

sudo apt-get install postgresql postgresql-contrib libpq-dev python-dev

然后我可以这样做:

 pip install psycopg2

以我为例，当我运行pip install -r requirements.txt在Ubuntu机器上安装带有PostgreSQL数据库的Django项目的所有包时，我遇到了这个错误和许多其他安装错误。

为了解决这个问题，我运行了以下命令:

sudo apt install postgresql postgresql-contrib  

sudo apt install libpq-dev

sudo apt install python3-dev

sudo apt install python3-pip

sudo apt install python3-psycopg2

pip3 install psycopg2

pip3 install psycopg2-binary

另外，还要检查Ubuntu、Python和Psycopg版本是否兼容。

另外，pip安装aiopg，解决了我第二次遇到它时的问题。
