Python 安装setuptools时出错（无序类型：str（）<；NoneType（））

Python 3.4.2，32位-Win 8.1，64位

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：

pip安装设置工具：

（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。）

下载并运行：

我认为卸载并重新安装python可以解决这个问题，但在尝试之前，我认为您可以帮助我找到问题的原因以及解决这个问题的正确方法。谢谢。

不要下载

ez_setup.py

，而是使用。从中，如果未安装

setuptools

，它将首先安装它

由于仍然会出现错误，请尝试从Christoph Gohlke的Windows存储库Python扩展包中安装和。确保您下载了Python 3.4的32位安装程序。下载后，运行

.exe

文件，希望一切都能恢复正常。那里有大量的科学计算软件包，所以如果你想与使用增强版numpy的英特尔MKL进行链接，那就去吧

在我看来，我的python安装完全搞砸了。这可能与几周前在我的系统上临时安装Python2有关。不管怎样，我认为卸载并重新安装整个东西对我来说会更容易。所以我卸载了python，然后重新安装，但这还不够。最后，我手动删除了

C:\Python34

并重新安装了python，现在它工作正常了。

我能够解决我的问题（在Win 8.1 64位上，python 3.4.2上），建议进行以下更改：

显然，

ez_setup.py

文件适用于Python 2，其中

'<（）

为

True

，即不是错误。这是建议使用的文件。你知道在哪里可以找到Python3版本吗？
