我正在尝试升级macOS上的numpy库,但是pip似乎没有足够的权限来删除numpy.运行`pip install –upgrade pip给我这个回溯：
➜ Desktop sudo -H pip install --upgrade numpy

Found existing installation: numpy 1.8.0rc1
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).
解决方法
面临同样的问题
sudo pip install –ignore-installed numpy
