cannot install because of psycopg2 requirement

alexzaitsev commented 5 years ago

I cannot install django-heroku because of psycopg2 requirement. But psycopg2-binary is already installed..

(env) p3ngu1ns-MacBook-Pro:bin p3ngu1n$ ./python pip install psycopg2-binary
Requirement already satisfied: psycopg2-binary in /Users/p3ngu1n/Documents/Develop/python/tutorials/producthuntclone/env/lib/python3.7/site-packages (2.8.3)
You are using pip version 18.1, however version 19.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

    Error: pg_config executable not found.

    pg_config is required to build psycopg2 from source.  Please add the directory
    containing pg_config to the $PATH or specify the full executable path with the
    option:

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

    or with the pg_config option in 'setup.cfg'.

    If you prefer to avoid building psycopg2 from source, please install the PyPI
    'psycopg2-binary' package instead.

    For further information please check the 'doc/src/install.rst' file (also at
    <http://initd.org/psycopg/docs/install.html>).

Me too, I don't have postgres installed on my local system and use postgres from somewhere else.

I'm facing the same issue as well.

@masato-io @alexzaitsev if you use Ubuntu, you can install llibpq-dev to solve this problem. I'm running latest linux mint.

sudo apt install libpq-dev
