psycopg: Python.h: No such file or directory

Question

I\'m compiling psycopg2 and get the following error: Python.h: No such file or directory

How to compile it, Ubuntu12 x64.

Answer 1

Python 2:

sudo apt-get install python-dev

Python 3:

sudo apt-get install python3-dev

Answer 2

This is a dependency issue.

I resolved this issue on Ubuntu using apt-get. Substitute it with a package manager appropriate to your system.

For any current Python version:

sudo apt-get install python-dev

For alternative Python version:

sudo apt-get install python<version>-dev

For example 3.5 as alternative:

sudo apt-get install python3.5-dev

Answer 3

As mentioned in psycopg documentation http://initd.org/psycopg/docs/install.html

Psycopg is a C wrapper around the libpq PostgreSQL client library. To install it from sources you will need:

• C compiler
• Python header files

They are usually installed in a package such as python-dev a message error such: Python.h: no such file or directory indicate that you missed mentioned python headers.

How you can fix it? First of all you need check which python version installed in your virtual envitonment or in system itself if you didnt use virtual environment. You can check your python version by:

python --version 

After it you should install the same python-dev version which installed on your virtual env or system. For example if you use python3.7 you should install

apt-get install python3.7-dev 

Hope my answer will help anyone

Answer 4

if you take a look at PostgreSQL's faq page ( http://initd.org/psycopg/docs/faq.html ) you'll see that they recommend installing pythons development package, which is usually called python-dev. You can install via

sudo apt-get install python-dev
