Psycopg2錯誤：clang：錯誤：未知參數：'-mno-fused-madd'[-Wunused-command-line-argument-hard-error-in-future]

Question

試圖以多種方式安裝psycopg2，但我不斷收到一個錯誤類同這一個：

我已經嘗試了許多命令，包括重新安裝PostgreSQL和Django的工具區。似乎沒有什麼區別，會出現相同的「類型」錯誤。我還將postgresql包含到我的$ PATH中：export PYTHONPATH=$PYTHONPATH:/Library/PostgreSQL/9.3/bin/pg_config

我在OSX Maverick上。我正在運行python 2.7和django 1.6。

任何想法？

Answer 1

我實際上並不知道答案，但是，當我使用所有有問題的組件時，我搜索了一下。我就遇到了這個：

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

所以，你可以嘗試這樣的：

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

看來問題是cc命令行參數包括那些沒有意義的CC和它曾經是一個軟錯誤，但現在它是一個致命的錯誤。祝你好運！
