试图重新安装python2.7 mac

Question

因此，当我尝试安装更多版本的 python（2.6、3.3）以尝试让 PyDev for eclipse 工作时，我在我的 python 中创建了一些问题。

这导致我（当时）工作版本的 python 2.7 出现问题

现在，我已经重新安装了 python 2.7。从终端我可以输入$python2.7 并获取：

    $ python2.7
    Python 2.7.6 (v2.7.6:3a1db0d2747e, Nov 10 2013, 00:42:54) 
    [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import sys
    >>> sys.path
    ['', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages']

对我来说这是一个好兆头。

然后，当我转到 $easy_install scipy 时，我得到：

    $ easy_install scipy
    error: can't create or remove files in install directory

    The following error occurred while trying to add or remove files in the
    installation directory:

        [Errno 2] No such file or directory: '/Library/Python/2.7/site-packages/test-easy-install-20589.write-test'

    The installation directory you specified (via --install-dir, --prefix, or
    the distutils default setting) was:

        /Library/Python/2.7/site-packages/

    This directory does not currently exist.  Please create it and try again, or
    choose a different installation directory (using the -d or --install-dir
    option).

所以，有了这个，我试图让它从黑暗的一面回来，并让 2.7 备份并运行。感谢您的帮助

您可能缺少指向您的 python 安装的符号链接。从命令行尝试：

sudo ln -s /Library/Frameworks/Python.framework/Versions/2.7 /Library/Python/2.7
