操作错误：[Errno 1]不允许操作

    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.

当我尝试sudo时：

操作不允许：/tmp/pip-JhNitO-卸载/系统/库/框架/Python.framework/Versions/2.7/Extras/lib/python/numpy-1.8.0rc1-py2.7.egg-info

我试图卸载Numpy。
但仍然发生权限错误：

OSError：[Errno 1]操作不允许：'/var/folders/dd/70hgtbs50hl5sr13h93gzzm80000gns/T/pip-yKfQhH-卸载/系统/库/框架/Python.framework/Versions/2.7/Extras/lib/python/numpy-1.8.0rc1-py2.7.egg-info'

对于sudo：

OSError:[Errno 1]不允许操作：'/tmp/pip-sIVZu9-uninstall/System/Library/Frameworks/Python。framework/Versions/2.7/Extras/lib/python/numpy-1.8。0rc1-py2。7.egg info“目录”/Users/jack/Library/Caches/pip/http”或其父目录不属于当前用户，缓存已被禁用。请检查该目录的权限和所有者。如果使用sudo执行pip，您可能需要sudo的-H标志。

最后，我试图卸载python通过pip卸载python，但有：

OSError:[Errno 1]不允许操作：'/var/folders/dd/70hgtbs50hl5sr13h93gzm8000gn/T/pip-7byw9-uninstall/System/Library/Frameworks/Python。framework/Versions/2.7/lib/python2。7/lib dynload/Python-2.7。10-py2。7.鸡蛋信息'

和sudo：

OSError:[Errno 1]不允许操作：'/tmp/pip-1UeP4t-uninstall/System/Library/Frameworks/Python。framework/Versions/2.7/lib/python2。7/lib dynload/Python-2.7。10-py2。7.egg info“
目录“/Users/jack/Library/Caches/pip/http”或其父目录不属于当前用户，缓存已被禁用。请检查该目录的权限和所有者。如果使用sudo执行pip，您可能需要sudo的-H标志。

所以我还递归删除了目录：

sudo rm -rf /tmp/pip-1UeP4t-uninstall/

但这些目录会立即复制。
