我正在尝试在运行Mavericks的Apple机器上更新python安装。我担心自己用自制软件破坏了东西。
当我尝试制表python时，我得到以下输出：
python python2.5-config python2.7 python3-config pythonw pythonw2.7 python-config python2.6 python2.7-config python3.3 pythonw2.5 pythonw3.3 python2.5 python2.6-config python3 python3.3-config pythonw2.6
运行where python会产生以下输出/usr/bin/python。同样，运行where python3会产生/usr/local/bin/python3和where python3.3会产生/usr/local/bin/python3.3。
当我分别运行每个不同的python可执行文件时，我得到以下输出：
$ 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 Type "help", "copyright", "credits" or "license" for more information. >>>

在PyCharm中，默认的可用解释器路径是：
/System/Library/Frameworks/Python.framework/Versions/2.5/bin/python /System/Library/Frameworks/Python.framework/Versions/2.6/bin/python /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python /usr/local/bin/pypy /usr/local/bin/python3 /usr/local/bin/python3.3 在PyCharm中选择/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python作为我的翻译，这表明我的几个软件包已经过时了。这些过时的包与我运行pip list -o时显示的相同：

尝试通过PyCharm更新numpy会导致以下错误：
Upgrade packages failed. The following command was executed: /Applications/PyCharm CE.app/helpers/packaging_tool.py install --build-dir /private/var/folders/7r/9rtxb7c94bv_k4szp8lnkpmm0000gn/T/pycharm-packaging258144586042338380.tmp -U numpy The error output of the command: Storing debug log for failure in /Users/myusername/Library/Logs/pip.log (1)
检查日志文件似乎是导致失败的原因
clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future] clang: note: this will be a hard error (cannot be downgraded to a warning) in the future clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future] clang: note: this will be a hard error (cannot be downgraded to a warning) in the future failure.
当我运行sudo pip install -U numpy
根据这些信息，我（希望正确地）得出结论，我正在尝试更新Apple提供的python，并且MacPorts可能更适合解决此任务。我安装了MacPorts并运行port upgrade outdated，结果为Nothing to upgrade。
如何从2.7.5更新到2.7.6并更新相关的包？
答案 0 :(得分：2)
问题是，小牛似乎已经破坏了构建python扩展。 mavericks上的python是使用较旧的编译器和较旧的选项构建的。这些选项存储起来供以后用于
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/_sysconfigdata.py
您可以手动编辑此文件以删除错误的编译器选项，或者您可以为您执行此操作：
sed -i 's/-mno-fused-madd//' /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/_sysconfigdata.py
我只在系统Python 2.7上测试并使用过它。我不知道你的/ usr / local python版本是否也能正常工作。使用自制软件或其他方法使用最新的编译器选项重建这些python实例可能更容易。
更新：您可能也更喜欢使用gcc而不是clang。见：https://stackoverflow.com/a/20295014/16998
