    DEPRECATION: Uninstalling a distutils installed project (numpy) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
    Uninstalling numpy-1.8.0rc1:

所以显然pip在删除/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy-1.8.0rc1-py2.7.egg-info时遇到了问题.尝试在finder中手动删除此文件会给我这个错误：

“numpy-1.8.0rc1-py2.7.egg-info” can’t be modified or deleted because it’s required by OSX.

我怎么解决这个问题？ (使用内置numpy不是一个选项,因为tensorflow,我需要的包,需要最新版本).
