Question

我在更新到Mac OS X Mountain Lion后遇到psycopg2错误，之前它运行正常。如果我尝试导入模块，这是错误：

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

我用brew来安装python和psycopg2。任何想法都会有所帮助。

Answer 1

尝试酿造postgresql。该错误可能与libpq（PostgreSQL客户端库，其中psycopg是包装器）的链接方式有关。

Answer 2

混合native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”，如pip install fails with /usr/bin/clang: No such file or directory中所述。然后重试pip install，它会起作用，至少它为我完成了工作！
