在Mavericks 10.9上试图通过pip安装psycopg2时,我得到以下错误:

clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]

不知道如何继续,已经在这里和其他地方搜索了这个特定的错误。任何帮助都非常感激!

以下是pip的完整输出:

当前回答

我使用自制程序安装postgresql,然后想在Mavericks上将psycopg2安装到系统提供的python 2.7中。为了让它工作,我最终运行了这个:

sudo ARCHFLAGS="-arch x86_64" CFLAGS=-Wunused-command-line-argument-hard-error-in-future pip install psycopg2

其他回答

对我来说,坏标志是在包的Makefile中显式给出的。因此,我必须编辑makefile以从错误包中删除无法识别的标记。

亚马逊Linux [AWS EC2]

试图在亚马逊Linux AMI发布2016.09上pip安装paramiko给了我一个错误,其中包括一个到这个SO帖子的链接。所以,即使它不符合OP的标题,我也要分享答案。

yum install libffi-devel
yum install gcc
yum install openssl-devel
pip install paramiko

_sysconfigdata.py修复的变体:使用虚拟环境

cp /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/_sysconfigdata.py ${VIRTUAL_ENV}/lib/python2.7/_sysconfigdata.py

然后编辑你的拷贝到${VIRTUAL_ENV}/lib/python2.7/_sysconfigdata.py

我删除了'-mno-fused-madd'的所有出现,然后构建在那个virtualenv中工作。

不需要根!

以上的方法对我来说都没用。我的情况略有不同。当我收到这个错误消息时,我正试图通过自制程序安装rdiff-backup。

我显然有苹果的默认python (2.7.5 @ /usr/bin/python)和Homebrew的python (2.7.6 @ /usr/local/Cellar/python/2.7.6/bin/python),但错误来自苹果的python。

为了解决这个问题,我基本上切换了python二进制文件。

我通过sudo做到了这一点:

cp /usr/蟒蛇/usr/bin/python_orig -在s /usr/local/Cellar/python/2.7.6/bin/python /usr/ python

然后,'brew install rdiff-backup'成功,没有任何错误。

最后,我执行“mv /usr/bin/python_orig /usr/bin/python”来还原所有内容。
