Ubuntuオペレーティングシステム上で直接pip install psycopg2はエラーを報告します

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

では、まずコマンドを実行します

sudo apt-get install libpq-dev

インストールを続行すれば、解決できます.
