Question

我在Windows 8.1机器上安装了一个干净的新版python。我尝试了Python 2.7.8和Python 3.4。

我从命令提示符运行python get-pip.py - 这正确地安装了pip。我是从here获得的。

之后我运行pip install mongo-connector。这会下载mongo连接器并抛出这样的异常：

  Downloading mongo-connector-1.3.tar.gz
  Running setup.py (path:c:\users\imon~1\appdata\local\temp\pip_build_èimon\mong
o-connector\setup.py) egg_info for package mongo-connector

如果是Python 3.4，它会抛出：

在没有任何参数的情况下运行pip会抛出这个：

在Python 2.7.8中运行pip会抛出这个：

Traceback (most recent call last):
  File "C:\Python27\lib\runpy.py", line 162, in _run_module_as_main
    "__main__", fname, loader, pkg_name)

    return codecs.charmap_encode(input,errors,encoding_map)

这种情况从未发生在我使用的任何其他机器上。我发现了许多类似的问题，但没有一个问题涉及我需要对我的案例做些什么。

This thread告诉我运行chcp 65001.当我这样做并且之后运行pip时，它会抛出这个：

根据this thread，可能问题是，用户名是“Šimon”，包含一个unicode字符。但是，我不知道，该怎么办。我不是要将任何python文件编辑为不同的编码，这似乎只是一个非常困难和临时的解决方法。（windows为我做了用户名 - 另一个糟糕的想法，不让我为我选择用户名。）

Answer 1

因为python不知道“cp65001”是“utf-8”的别名你可以在windows中设置它：

set PYTHONIOENCODING=utf-8

Answer 2

这是一种解决方法，而不是问题的解决方案。我在Windows中的用户名自动为“Šimon”。 “Š”是一个问题。我找到了重命名用户名的方法，但之后很多事情都停止了。 Windows注册表充满了散落在该地方的“Šimon”，必须使用特殊工具一次性重命名它们，并且用户文件夹中的许多链接停止工作。包括％APPDATA％和其他类似文件夹 - 因此许多软件停止工作，在启动时抛出意外错误，包括Dropbox，XMind等。

因此，如果问题是从根本上解决的话会很好，因为这种解决方法很难正确执行，但仍然无法解决问题。

Answer 3

这是一个pip bug，两年后仍未正确修复。见https://github.com/pypa/pip/issues/1291。按照@YRUsoDiao的建议设置PYTHONIOENCODING不会解决问题，因为env var只影响stdin / stdout / stderr。现在，在运行＆＃34; pip install＆＃34;之前，您必须更改您的Windows帐户才能使用CP65001（UTF-8）。如果setup.py模块包含除纯ASCII之外的utf-8序列。

Python - 另一个编码问题。 Windows 8.1，两个最新的蟒蛇。 pip抛出异常
