Ubuntu上pip install psycopg2報錯pg_config executable not found

參考 https://stackoverflow.com/questions/11618898/pg-config-executable-not-found

在Ubuntu操作系統上直接pip install psycopg2是會報錯的

Error: pg_config executable not found.

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'.

----------------------------------------
Command python setup.py egg_info failed with error code 1 in /tmp/pip-build/psycopg2

那麼，先運行命令

sudo apt-get install libpq-dev

再繼續安裝，就可以解決
