I am trying to put my app that I created on server www using heroku. But when I put to my terminal on Ubuntu pip install psycopg2==2.7.*, I get this error:

    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>).

You need some dependencies check this answer https://stackoverflow.com/a/46877364/15208727

sudo apt install libpq-dev python3-dev

CodePudding user response：

You should install pscopg2-binary and the push to heroku

pip install psycopg2-binary or pipenv install psycopg2-binary depending on your virtualenv
