Problem installing pyscopg2 on mac os x

Question

I downloaded the latest pyscopg2 assembly and tried to build and install it using the provided instructions. However, I always get an error that "w" is not declared. Does anyone have any experience with this?

Answer 1

This is an error that occurs when the build tools cannot find your Postgresql libraries. This means one of three things:

• You do not have postgresql installed on your system. If so, download and create postgres, or download the pre-created psycopg2 binary for OS X.

• postgresql , , , , psycopg2. postgres.

• , postgres psycopg2, pg_config, . :

  . pg_config ( /usr/local/pgsql/bin/, postgres , .

  . setup.cfg psycopg2 pg_config , pg_config=. , . postgres, , :

  pg_config=/usr/local/pgsql/bin/pg_config
