Python 使用brew在osx上安装scipy时出错

我正在尝试使用brew在我的osx 10.9计算机上安装scipy，但安装一直失败：

administrators-iMac-3:sourcefind_python bill$ brew install scipy --default-fortran-flags
==> Using Homebrew-provided fortran compiler.
This may be changed by setting the FC environment variable.
==> Building with an alternative Fortran compiler
This is unsupported.
Warning: No Fortran optimization information was provided.  You may want to consider
setting FCFLAGS and FFLAGS or pass the `--default-fortran-flags` option to
`brew install` if your compiler is compatible with GCC.

If you like the default optimization level of your compiler, ignore this
warning.

我安装了gcc，它应该包含gfortran：

administrators-iMac-3:sourcefind_python bill$ brew install gfortran
Error: No available formula for gfortran
GNU Fortran is now provided as part of GCC, and can be installed with:
  brew install gcc

administrators-iMac-3:sourcefind_python bill$ brew install gcc
Warning: gcc-4.8.3_1 already installed

应该有：

administrators-iMac-3:sourcefind_python bill$ gfortran
gfortran: fatal error: no input files
compilation terminated.

看起来fortran编译器有问题。当我使用OSX和Homebrew for SciPy时，我通常也会安装gfortran以在SciPy中编译fortran文件

试着做：

brew install gfortran

---

然后重试。

要解决此问题，您必须使用另一版本的

gfortran

。文中给出了详细的解释

您可能还想尝试使用可用的.dmg安装程序进行安装

谢谢，我应该通过brew install gcc安装gfortran（我想）是否有任何方法进行测试？如果您从命令行运行

gfortran

，它应该响应没有/没有不正确的输入文件。否则未安装或系统找不到它。试试这个？根据个人经验，我必须单独安装gfortran。我相信这是因为在安装gcc时，它允许gcc编译fortran文件，但是SciPy专门寻找gfortran。我假设您在没有默认fortran标志选项的情况下尝试过它？这本不必要；scipy通常与酿造的gfortran（来自gcc配方）配合使用。这里有一个建议：重新安装libmpc。
