在OSX上更新Python及其包

Question

我正在尝试在一台运行Mavericks系统的苹果电脑上更新Python的安装。我担心我在使用Homebrew的时候搞砸了。

当我尝试使用自动补全输入python时，出现了以下输出：

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命令的结果是/usr/bin/python。同样，运行where python3的结果是/usr/local/bin/python3，而运行where python3.3的结果是/usr/local/bin/python3.3。

当我分别运行不同的Python可执行文件时，得到的输出如下：

$ 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

$ python3

在PyCharm中，默认可用的解释器路径有：

/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作为我的解释器时，显示有几个包是过时的。这些过时的包和我运行pip list -o时显示的相同：

尝试通过PyCharm更新numpy时出现了以下错误：

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)

查看日志文件后，似乎是这个导致了失败：

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时，也得到了同样的错误。

根据这些信息，我（希望是正确的）得出结论，我正在尝试更新苹果提供的Python，可能使用MacPorts会更适合解决这个问题。我安装了MacPorts并运行了port upgrade outdated，结果是Nothing to upgrade。

我该如何将版本从2.7.5更新到2.7.6，并更新相关的包呢？
