How to Resolve \'pg_config\' Executable Issue for psycopg2 Installation in Python?

Resolving Installation Issue for psycopg2 with "pip" on Python

In an attempt to install psycopg2 via pip, you encountered an error indicating the absence of the pg_config executable. To resolve this issue, you can choose one of the following options:

Option 1: Install Psycopg2 Binary Package

Install the pre-compiled binary wheel of psycopg2, which avoids the need to build the package from source. For this, execute:

pip install psycopg2-binary

Option 2: Build Psycopg2 from Source

Ensure you have the prerequisites for building the psycopg2 package:

Debian/Ubuntu:

Python Version	Command	Note
Default Python 3	sudo apt install libpq-dev python3-dev
Python 3.x	sudo apt install libpq-dev python3.x-dev	Replace "x" with the desired Python version
Python 2	sudo apt install libpq-dev python-dev

After installing the prerequisites, build the package with the following command:

python setup.py build_ext --pg-config /path/to/pg_config build ...

Replace "/path/to/pg_config" with the actual path to the pg_config executable.
