Proposed fix: [psycopg2] 'Error: pg_config executable not found.' (and 'libpq-fe.h: No such file or directory') building from source — install libpq dev package / put pg_config on PATH, or use psycopg
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Either install build prerequisites (C compiler, python3-dev, libpq-dev; add /usr/lib/postgresql/X.Y/bin to PATH if pg_config is elsewhere) or switch to psycopg2-binary for dev/test (the project advises source builds for production and for library dependencies).
Option: Install libpq dev files [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. Debian/Ubuntu: apt-get install -y build-essential python3-dev libpq-dev
2. Check pg_config --version; export PATH=/usr/lib/postgresql/X.Y/bin:$PATH if needed
3. pip install psycopg2
Expected: Command proceeds without the error.
Option: Use the binary package (dev/test) [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. pip install psycopg2-binary
Expected: Command proceeds without the error.
