一直在尝试以多种方式安装 psycopg2，但我不断收到与此类似的错误：

我尝试了很多命令，包括重新安装 postgresql 和 django-toolbelt。似乎没有什么不同，会发生相同的“类型”错误。我还将 postgresql 包含到我的 $PATH 中：export PYTHONPATH=$PYTHONPATH:/Library/PostgreSQL/9.3/bin/pg_config

我在 OSX Maverick 上。我正在运行 python 2.7 和 django 1.6。

有什么想法吗？

【解决方案1】：

我实际上并不知道答案，但是，我搜索了一下，因为我使用了您遇到问题的所有组件。我遇到了这个：

http://kaspermunck.github.io/2014/03/fixing-clang-error/

所以，你可以试试这样的：

sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install psycopg2

问题似乎在于 cc 命令行包含对 cc 没有意义的参数，并且它曾经是一个软错误，但现在它是一个致命错误。祝你好运！
