쿠...sal: [컴][파이썬] virtualenv 에서 psycopg2 설치하기

pip install psycopg2

virtualenv 에서 pip 로 psycopg2 를 설치하려고 한다.

pg_config path 설정

pip 로 psycopg2 를 설치하는데, pg_config 가 필요해서, 이 pg_config 가 있는 곳의 path 를 지정해줘야 한다. PostgreSQL 의 path 에 "(쌍따옴표) 가 없는 것에 주의하자.

(spike) d:\mine\programming\python\spikeroot\spike>set PATH=%PATH%;d:\Program Files (x86)\PostgreSQL\9.3\bin

이렇게 하고 pip install psycopg2 를 하면 아래처럼 UnicodeEncodeError 가 난다. 관련해서 찾아보니 c/c++ library 를 compile 해서 설치하기 위해서는 python-dev 가 필요하다.[참고]

그렇게 하기는 좀 그래서 다른 방법을 찾아봤다.

easy install

그래서 아래 글을 찾았다.

방법은 easy install 이다. 아래는 python 2.7 64-bit 버전을 설치한 경우이다.

easy_install http://www.stickpeople.com/projects/python/win-psycopg/2.6.1/psycopg2-2.6.1.win-amd64-py2.7-pg9.4.4-release.exe

위의 글에 따르면 virtualenv 에서도 가능하다고 한다. 실제로 해보니 잘 됐다.
