Eu instalei o Anaconda com o python 2.7.7.
No entanto, sempre que executo "importar pandas", recebo o erro:
"ImportError: C extension: y not built. If you want to import pandas from the source directory, you may need to run 'python setup.py build_ext --inplace' to build the C extensions first."
Eu tentei executar o comando sugerido, mas ele afirmou que

skipping 'pandas\index.c' Cython extension (up-to-date)      
skipping 'pandas\src\period.c' Cython extension (up-to-date) 
skipping 'pandas\algos.c' Cython extension (up-to-date)

skipping 'pandas\src\testing.c' Cython extension (up-to-date)
skipping 'pandas\msgpack.cpp' Cython extension (up-to-date)

Alguém já encontrou isso antes e encontrou uma solução?
