The package `libpq-dev` is required in order to install from source on Raspbian/Raspberry Pi. On a fresh install of Raspbian on a Raspberry Pi, the source install will fail on the `psycopg2` step: ``` Collecting psycopg2>=2.6; extra == "all" (from matrix-synapse[all]) Using cached https://files.pythonhosted.org/packages/23/7e/93c325482c328619870b6cd09370f6dbe1148283daca65115cd63642e60f/psycopg2-2.8.2.tar.gz ERROR: Complete output from command python setup.py egg_info: ERROR: running egg_info creating pip-egg-info/psycopg2.egg-info writing pip-egg-info/psycopg2.egg-info/PKG-INFO writing dependency_links to pip-egg-info/psycopg2.egg-info/dependency_links.txt writing top-level names to pip-egg-info/psycopg2.egg-info/top_level.txt writing manifest file 'pip-egg-info/psycopg2.egg-info/SOURCES.txt' 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>). ---------------------------------------- ERROR: Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-l2ooiex9/psycopg2/ ``` The solution is to install the package `libpq-dev` with `sudo apt-get install libpq-dev` since this is where the `pg_config` executable is found.

Thanks for this, but we're going down the path of #5197 instead. |
