Question

我想使用brew安装numpy的工作版本。 brew install numpy给出了以下信息：

==> python setup.py build --fcompiler=gnu95 install --prefix=/usr/local/Cellar/numpy/1.8.1
File "/private/tmp/numpy-ncUw/numpy-1.8.1/numpy/distutils/fcompiler/gnu.py", line 197, in get_flags_opt
v = self.get_version()
File "/private/tmp/numpy-ncUw/numpy-1.8.1/numpy/distutils/fcompiler/__init__.py", line 434, in get_version
raise CompilerNotFound()
numpy.distutils.fcompiler.CompilerNotFound

brew doctor没关系，所以它实际上可能是一个缺少的fortran编译器问题。尝试：brew install gfortran

Error: No available formula for gfortran

咦。根据brew GitHub issue tracker中的评论，看起来gfortran不再是酿造品。让我们尝试从the project website下载gfortran 4.9.0并设置FC=\path\to\gfortran以便brew知道使用它

Drat，所以brew 并不想使用非默认的fortran编译器。我默认安装了llvm的OSX 10.9，所以对添加gcc安装很谨慎。当llvm接手时，许多程序必须重新编译，因此更改默认编译器（再次）似乎很危险。

非常欢迎任何关于如何酿造以完成安装的建议。

brew install gcc

Numpy安装现在运行正常。

用自制软件安装gfortran for numpy
