Clang错误:未知参数:'-mno-fused-madd' (python包安装失败)

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

你可能使用的是Python 2.7.5

$ python

Python 2.7.5 (default, Aug 25 2013, 00:04:04)  [GCC 4.2.1 Compatible
Apple LLVM 5.0 (clang-500.0.68)] on darwin

最简单的解决方案是去www.python.org并安装与LLVM 5.1兼容的Python 2.7.6。

然后吐司您的旧虚拟环境rmvirtualenv {virtual_env_name}。

然后创建一个新的虚拟环境。

mkvirtualenv --no-site-packages -p/Library/Frameworks/Python.framework/Versions/2.7/bin/python {virtual_env_name}

在此之后PIP应该可以正常工作。

xCode 5.1

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

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
2014-03-26 16:36:55

_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!

我还编辑了系统python的原始编译标志的概念(正如@user3405479所做的那样)。我没有使用编辑器，而是使用命令行工具“就地”编辑文件(inode会发生变化)。我还编译了新的pyo和pyc文件，而不是删除它们。

以下命令以root用户运行，例如在sudo -i下运行

pushd /系统/图书馆/框架/ Python.framework /版本/ 2.7 / lib / python2.7

Sed 's/-mno-fused-madd//g' _sysconfigdata.py \ | diff -p _sysconfigdata.py - | patch -b . sh

Python -m py_compile _sysconfigdata.py

python -OO -m py_compile _sysconfigdata.py

popd

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。
