更新到 Mac OS X Mountain Lion 后出现 psycopg2 错误，之前它工作正常。如果我尝试导入模块，这是错误：

    Python 2.7.3 (default, Sep 27 2012, 21:57:16)

>>> import psycopg2

我使用 brew 来安装 python 和 psycopg2。任何想法都会有所帮助。

谢谢亚历克斯

也尝试酿造 postgresql。错误可能在于 libpq（PostgreSQL 客户端库，其中 psycopg 是一个包装器）的链接方式。

混合原生和 brew 应用程序并不是那么好......我宁愿从 brew 卸载 psycopg2 和 python 并安装“命令行工具”，就像pip install failed with /usr/bin/clang: No such file or directory中解释的那样。然后重试 pip install ，它会工作，至少它为我完成了工作！
