python - Numpy 安装/构建 Mac Osx

Question

所以我按照本网站上的说明进行操作 http://www.scipy.org/Installing_SciPy/Mac_OS_X ，下载 Xcode 和 Fortran Gcc，然后从终端运行以下命令:

我已经为此工作了几个小时，现在迷路了。

下载 Xcode 4 后，您需要安装它的 Command Line Tools 组件。启动 Xcode，然后选择 Xcode -> Preferences -> Downloads -> Components .这将安装 clang 和其他构建工具，以便可以从命令行使用它们。
