    Traceback (most recent call last):

Psycopg2 以前工作正常，但现在出现此错误。

关于这个问题的任何想法都非常感谢。

编辑：所以在每次设置我的 mac 时处理这么多 psycopg2 错误之后，我决定使用运行 Ubuntu 的 VMWareFusion 来代替。

Psycopg2 was working fine before, but now I get this error.

Any ideas on this issue much appreciated.

EDIT: so after dealing with so many psycopg2 errors everytime I set up my mac, I've decided to use VMWareFusion running Ubuntu instead.

难道是 postgres 安装被删除/更新了吗？该符号应该来自 libpq。

这对我来说也很糟糕，就我而言，这似乎不是 32 位与 64 位的问题：

This is broken for me too, and in my case it doesn't appear to be a 32 vs 64 bit issue:
