Python 3.4.2, 32 bit - Win 8.1, 64 bit

首先我尝试升级 setuptools，但没有成功.所以我决定卸载以前的版本.现在我无法安装 setuptools.我尝试了以下方法:

First I was trying to upgrade setuptools, but it was not successful. So I decided to uninstall the previous version. Now I can't install setuptools. I have tried the following:

1. pip 安装设置工具:

1. pip install setuptools:

Exception:

运行 (Invoke-WebRequest https://bootstrap.pypa.io/ez_setup.py).Content |python - 在具有管理员权限的 powershell 中:

(我现在不愿意安装 Internet Explorer，但如果您认为我必须安装，那么我会安装.)

(I'm not willing to install Internet Explorer right now, but if you think I have to, then I will.)

1. 下载 ez_setup.py 并运行它:

TypeError: unorderable types: str() < NoneType()
Something went wrong during the installation.
See the error message above.

通过运行 python-3.4.2.msi 并选择修复选项来修复 python 安装.但仍然没有设置工具:

Repairing python installation by running python-3.4.2.msi and choosing the repair option. But still no setuptools:

>pip install scipy -U
Collecting scipy from https://pypi.python.org/packages/source/s/scipy/
.0.tar.gz#md5=639112f077f0aeb6d80718dc5019dc7a
  Using cached scipy-0.15.0.tar.gz
  setuptools must be installed to install from a source distribution

我认为卸载并重新安装 python 可以解决问题，但在尝试之前，我想也许您可以帮助我找到问题的原因以及解决此问题的正确方法.谢谢.

I think uninstalling and reinstalling python would fix the problem, but before trying that I thought maybe you can help me to find the cause of the problem and the right way to fix this. Thanks.
