如何使用PIP安装Coremltools 4.0版，而无需在Mac上安装错误？
我已经使用pyenv创建了Python 2.7.13的外壳环境，但是当我进行PIP安装时，coremltools == 4.0'我会收到五个错误消息，如下所示；
ERROR: Exception:

我认为Python 2.7.13和Coremltools 4.0之间存在一些兼容性问题。
我正在关注Angela Yu关于iOS开发的课程，并且在机器学习的部分中，她使用Python 2.7和Coremltools将CAFFE模型转换为.mlModel文件。但是该课程已经快3岁了，我的Mac没有相同版本的Python和Coreltools。
我完全不熟悉Python，我真的很感谢您的帮助。
I have used pyenv to create a shell environment of python 2.7.13 but when I do pip install 'coremltools==4.0' I get five error messages as below;

I think there is some compatibility issue between Python 2.7.13 and coremltools 4.0.
I am following Angela Yu's course on iOS Development and I am at the section on machine learning where she uses Python 2.7 and coremltools to convert a Caffe model into a .mlmodel file. But the course is nearly 3 years old and my mac doesn't have the same version of Python and coreltools.
I am completely unfamiliar with Python and I would really appreciate some help.

此错误来自环境本身，看起来并不针对Coremltools。您能否按照
This error is from environment itself and does not look specific to coremltools. Could you please follow steps from https://coremltools.readme.io/docs/installation and see if you find any issues?
您正在使用哪个版本的
pip？它对我有用，也许在创建您的环境时（如果使用Conda）
