Python 2.7，PIP:"...的构建轮子失败"； [英] Python 2.7, PIP: "Failed building wheel for ..."

问题描述

第一次使用pip，尝试使用 python-docs-samples教程库 .当我运行"python -m pip install -r requirements.txt"命令时，引入了许多脚本，但是随后出现一系列"Failed building wheel"错误.其中的一个显示在所附的代码块中(请原谅手动输入的自动换行符).

First time using pip, trying to use the python-docs-samples tutorial library. When I run the "python -m pip install -r requirements.txt" command, a lot of scripts are pulled in, but then I get a series of "Failed building wheel" errors. One of these is shown in the attached code block (please pardon the hand-entered word-wrap linebreaks).

出什么问题了?有人看过吗?我没有更改库的任何部分或使用它的代码，并且我使用的是Python 2.7.12，它应该对PIP具有良好的内置支持.

What is the problem? Anyone seen this before? I have not altered any parts of the library or the code that uses it, and I'm using Python 2.7.12 which is supposed to have good built-in support for PIP.
