    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:

这是我遇到的错误。我尝试了各种命令，这是我遇到的一般错误。这是我输入时的完整回复

pip install coremltools

在我的终端上 window

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。它们可以通过使用 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主意。很难清理它，删除库。这也会破坏系统的行为（因为它取决于 Python 及其特定的库及其特定版本）。

相反，创建您的 virtualenv，并在那里处理您的项目：

which pip

virtualenv myenv
source myenv/bin/activate

which pip

pip install coremltools

python
>>> import coremltools

这是官方推荐的将项目与系统（以及系统与项目）隔离开来的方法。有关详细信息，请阅读文档：https://virtualenv.pypa.io/
