导入psycopg2

Question

我正在尝试导入pscycopg2。我在运行时遇到滚动错误import psycopg2：

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 

我被困在它。请帮忙。

Answer 1

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

检查您的DYLD_LIBRARY_PATH并确保最新的PostgreSQL libpq.5.dylib在路径上第一个。
