Psycopg2錯誤：叮當聲：錯誤：未知參數：'-mno-fused-madd'[-Wunused命令行參數參數硬錯誤在將來]

Question

試圖以多種方式安裝psycopg2，但我不斷收到與此類似的錯誤：

我嘗試了許多命令，包括重新安裝postgresql和django-toolbelt。 似乎沒有什么改變，會發生相同的錯誤“類型”。 我還將postgresql包含在$ PATH中，包括： 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。

有任何想法嗎？

Answer 1

我實際上不知道答案，但是，當我使用遇到問題的所有組件時，我進行了一些搜索。 我遇到了這個：

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

因此，您可以嘗試執行以下操作：

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

似乎問題在於cc命令行包含的參數對於cc而言沒有意義，它曾經是一個軟錯誤，但現在是致命錯誤。 祝好運！
