进口psycopg2

Question

我正在尝试导入pscycopg2。我在运行import psycopg2时遇到了滚动错误

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.7/site-packages/psycopg2/__init__.py", line 50, 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: _lo_lseek64
  Referenced from: /Library/Python/2.7/site-packages/psycopg2/_psycopg.so
  Expected in: /usr/lib/libpq.5.dylib in /Library/Python/2.7/site-packages/psycopg2/_psycopg.so

我被困住了。请帮帮忙。

您的psycopg2是针对较新的PostgreSQL libpq编译的，而不是OS系统在运行时加载的libpq。您可能安装了多个版本的PostgreSQL。

检查您的DYLD_LIBRARY_PATH并确保最新的PostgreSQL libpq.5.dylib在第一条路径上。
