Build gives multiple errors on pg_config
I am trying to build the course (thinkcspy) by using the build.sh file.
I get many errors like this, and have no idea what I have done incorrectly.

Found that I have to install libpq-dev
The build now works, but the code examples do not show up when I use runestone serve, which says:
Connecting to DB
Cannot configure a Database URL!
Skipping all DB operations because environment variables not set up
Where might I get guidance on setting this up properly?
The main problem is that build.sh should have been deleted years ago... 😬
Try:
pip install -r requirements.txt
runestone build --all
The problem is it is trying to build psycopg2 rather than use psycopg2-binary in order to build psycopg2 from source you need to have the postgresql development set up. With psycopg2-binary properly installed it will do the right thing even if you do not have any database set up.
