Обсуждение: installation problems on OSX Lion
Hi I'm running OSX Lion and trying to install psycopg2 2.4.2 using PIP. The installation finishes successfully. But then I get the following error when trying to import: Python 2.7.1 (r271:86832, Jun 16 2011, 16:59:05) [GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import psycopg2 Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Python/2.7/site-packages/psycopg2/__init__.py", line 67, in <module> from psycopg2._psycopg import BINARY, NUMBER, STRING, DATETIME, ROWID ImportError: dlopen(/Library/Python/2.7/site-packages/psycopg2/_psycopg.so, 2): Symbol not found: _PQbackendPID Referenced from: /Library/Python/2.7/site-packages/psycopg2/_psycopg.so Expected in: flat namespace in /Library/Python/2.7/site-packages/psycopg2/_psycopg.so >>> Anybody know how to fix this? -Sean

They are in Google. Yes, I believe there's plenty of solutions, googling for them. An index is here: <http://initd.org/psycopg/articles/2010/11/11/links-about-building-psycopg-mac-os-x/>. if you find new troubles with Lion feel free to add a comment to the article, thanks. -- Daniele

They are in Google. Honestly, if someone can figure out how to subscribe + post to a mailing list, don't you think they'll know how to use Google? > Yes, I believe there's plenty of solutions, googling for them. > > An index is here: > <http://initd.org/psycopg/articles/2010/11/11/links-about-building-psycopg-mac-os-x/>. > if you find new troubles with Lion feel free to add a comment to the > article, thanks. The link you sent is from 2010. A lot has changed with OSX since then. Building on each version of OSX is quite different. I gave up trying to get it to work with our current install (PostgreSQL 8.4). I upgraded to PostgeSQL 9 and that finally allowed psycopg to install using PIP. Hope this helps for somebody else. Sean
