Hello @albarrentine and @Phil Hutchinson

I have followed the steps and was able to execute successfully on Ubuntu 20.04 LTS but still unable to import address_parser saikiran@saikiran-virtual-machine:~$ pkg-config --cflags libpostal

I use libpostal with python binding. A good way to use libpostal python binding is to install this library pylibpostal 1.0.0 instead.

When I used pylibpostal 1.0.0 in my environment(Centos 7, Jupyter notebook), I met this issue. The reason is that my jupyter notebook cannot read the environment variable LIBPOSTAL_DATA_DIR that path storing the data files of libpostal. Hence, I explicitly set the environment variable LIBPOSTAL_DATA_DIR in my code before importing the pylibpostal os.environ['LIBPOSTAL_DATA_DIR']='your absolute path to store data files of libpostal'
