How to install psycopg2 with pg_config error?

I've tried to install psycopg2 (PostgreSQL Database adapater) from this site, but when I try to install after I cd into the package and write python setup.py install I get the following error: 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'. I've also tried 'sudo pip install psycopg2' and I got the same message. After reading through the docs, it asks to look at the setup.cfg file (which is below): [build_ext] define= # PSYCOPG_DISPLAY_SIZE enable display size calculation (a little slower) # HAVE_PQFREEMEM should be defined on PostgreSQL >= 7.4 # PSYCOPG_DEBUG can be added to enable verbose debug information # "pg_config" is required to locate PostgreSQL headers and libraries needed to # build psycopg2. If pg_config is not in the path or is installed under a # different name uncomment the following option and set it to the pg_config # full path. #pg_config= # Set to 1 to use Python datetime objects for default date/time representation. use_pydatetime=1 # If the build system does not find the mx.DateTime headers, try # uncommenting the following line and setting its value to the right path. #mx_include_dir= # For Windows only: # Set to 1 if the PostgreSQL library was built with OpenSSL. # Required to link in OpenSSL libraries and dependencies. have_ssl=0 # Statically link against the postgresql client library. #static_libpq=1 # Add here eventual extra libraries required to link the module. #libraries= However, I'm not sure if I'm suppose to edit this file, since the documentation states the following: then take a look at the setup.cfg file. Some of the options available in setup.cfg are also available as command line arguments of the build_ext sub-command. For instance you can specify an alternate pg_config version using: $ python setup.py build_ext --pg-config /path/to/pg_config build Use python setup.py build_ext --help to get a list of the options supported. I've gotten the list of options supported but I'm not sure where to go from there
If you are on Ubuntu or any other debian-based distro, try sudo apt-get install python3-psycopg2 Otherwise, you need to find and install the Postgresql client packages for your distribution. psycopg2 installation from source
