Windows 8.1上的pip安装flake8中的UnicodeDecodeError [英] UnicodeDecodeError in pip install flake8 on Windows 8.1

问题描述

我正在尝试为Python安装flake8模块(以便使用SublimeLinter-flake8包来实现Sublime Text 3)，但是在安装时收到错误消息(如下).我在这里做什么错了?

I'm trying to install the flake8 module for Python (in order to use the SublimeLinter-flake8 package to Sublime Text 3) but get an error message on install (below). What am I doing wrong here?

C:\Windows\system32>python -m pip install flake8
Collecting flake8

推荐答案

在 Padraic 的慷慨帮助之后，我们最终发现问题出在我的计算机名称上，它是Fredrik-Bärbar(请注意，在使用python 0基于索引的代码页850中，ä，即0xe4，位于第10位或第9位).

After startlingly generous help from Padraic, we eventually figured out that the problem was my computer name, which was Fredrik-Bärbar (notice the ä, i.e. 0xe4 in code page 850, there in the 10th place, or 9th place using Python's 0-based indexing).

(此错误与安装时的提示错误中的错误有关，另一个问题由Padraic.)

(This error is related to that in Pip Error when installing, another question solved by Padraic.)
