python - scipy osx 10.9 无法加载 gfortran 库

Question

我尝试使用 pip 和brew 安装 scipy，但两次安装都出现此错误

ImportError: dlopen(/usr/local/lib/python2.7/site-packages/sklearn/linear_model/cd_fast.so, 2): Library not loaded: /usr/local/lib/gcc/x86_64-apple-darwin12.5.0/4.8.3/libgfortran.3.dylib
  Referenced from: /usr/local/lib/python2.7/site-packages/sklearn/linear_model/cd_fast.so
  Reason: image not found

查找有问题的库会显示可用的不同架构的版本:

administrators-iMac-3:sourcefind_python bill$ locate libgfortran.3.dylib
/Applications/MATLAB_R2013a.app/sys/os/maci64/libgfortran.3.dylib
/usr/local/Cellar/gcc/4.8.3_1/lib/gcc/x86_64-apple-darwin13.2.0/4.8.3/i386/libgfortran.3.dylib
/usr/local/Cellar/gcc/4.8.3_1/lib/gcc/x86_64-apple-darwin13.2.0/4.8.3/libgfortran.3.dylib

我确实尝试在/usr/local/lib/gcc/x86_64-apple-darwin12.5.0/4.8.3/libgfortran.3.dylib 放置一个符号链接(symbolic link)以指向 usr/local/Cellar/gcc/4.8。 3_1/lib/gcc/x86_64-apple-darwin13.2.0/4.8.3/libgfortran.3.dylib 但这给了我一个错误“错误的架构”

有人对让它发挥作用有什么建议吗？

Scikit-learn 正在寻找旧版本的 fortran 库。您应该重新安装 scikit-learn。
