ImportError：无法导入名称“编译”

Question

我正在尝试在我的 Mac（OSX El Capitan 版本 10.11.1）上安装 python 3.4 和 TensorFlow。
我按照这里的说明进行操作

Pip Installation

我可以的

$ sudo easy_install pip
$ sudo easy_install --upgrade six  

但这部分变得困难：

$ sudo pip install --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl  

我输入了密码； 它给了我一个回溯：

Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/pkg_resources/__init__.py", line 2859, in _dep_map
return self.__dep_map

raise AttributeError(attr)
AttributeError: _DistInfoDistribution__dep_map

在处理上述异常的过程中，又发生了一个异常：

Traceback (most recent call last):

我错过了什么重要信息吗？

Answer 1

这个错误的主要原因是你试图安装的包是一个Python 2的wheel文件。 （URL 中的py2 是这方面的线索此外，正如 Guy Coder 在 cmets 中指出的那样，您正在安装不支持 Python 3 的 TensorFlow 0.5.0 版。）

最好的解决方案是安装Python 3–compatible package:

$ sudo pip install --upgrade http://storage.googleapis.com/tensorflow/mac/tensorflow-0.6.0-py3-none-any.whl

（在网站上似乎很难找到这些链接，因此我们会尽快修复。）
