Solving Error: pg_config executable not found psycopg2 install
On my mac machine, I tried to install a new python library with psycopg2 in it, I got pg_config error, here’s how I solve this error
Case: When I try to add a new package on my computer that has psycopg2 library, it shows me this error
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 <https://www.psycopg.org/docs/install.html>). [end of output] note: This error originates from a subprocess, and is likely not a problem with pip. error: metadata-generation-failed × Encountered error while generating package metadata. ╰─> See above for output. ..
How I solve it
On mac, I need to install postgre first, we can install it with homebrew
brew install postgresql
Then try to install any package, now the error will be gone
