Psycopg2 fails to install on python 3 with pip issuing a fatal error

Loaded plugins: langpacks, refresh-packagekit
Package python3-3.3.2-8.fc20.x86_64 already installed and l         


        

Answer 1

Install the python3-devel package to get it work

sudo dnf install python3-devel

If it works then alright or if it requires libpq-fe.h file then install it using the command:

sudo dnf install postgresql-devel

Answer 2

On Ubuntu. I solved this with:

sudo apt-get install libpq-dev

Answer 3

You are missing python3 include files

./psycopg/psycopg.h:30:20: fatal error: Python.h: No such file or directory

you can probably find them in the python3-devel package.

Answer 4

As indicated in the other answers this is caused by not having the right Python "devel" package installed. On CentOS, the Python "devel" rpm package is numbered with the with the qualified version. For example as of this writing the current versions are:

python34-devel for epel repository

python36u-devel for ius repository

Example Yum command (assumes EPEL repository is configured):

sudo yum install python34-devel
