Requirement already satisfied: numpy>=1.6.2 in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python (from coremltools)
Collecting protobuf>=3.1.0 (from coremltools)
  Using cached protobuf-3.4.0-py2.py3-none-any.whl
Collecting six==1.10.0 (from coremltools)
  Using cached six-1.10.0-py2.py3-none-any.whl
Requirement already satisfied: setuptools in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python (from protobuf>=3.1.0->coremltools)
Installing collected packages: six, protobuf, coremltools
  Found existing installation: six 1.4.1
    DEPRECATION: Uninstalling a distutils installed project (six) 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 six-1.4.1:

这是我得到的错误。我尝试了各种命令，这是我得到的一般错误。这是我输入

时的完整回复

P.S。我正在使用macOS High Sierra。

因为您使用系统Python中的pip。写入系统文件夹，包括系统的Python需要root权限。可以使用sudo：

来实现

sudo pip install coremltools

但是，请记住，将库安装到系统中并不是最好的选择。它很难清理，删除库。这也可能破坏系统的行为（因为它依赖于Python及其特定的lib及其特定版本）。

相反，创建你的virtualenv，并在那里处理你的项目：

which pip

virtualenv myenv
source myenv/bin/activate

which pip

pip install coremltools

python
>>> import coremltools

这是将项目与系统（以及系统与项目）隔离的推荐官方方式。有关详细信息，请阅读文档：https://virtualenv.pypa.io/

我无法在我的mac上执行任何pip命令
