How to upgrade my Python version on Windows 7 without having to re-install all packages?
提问by Puggie
What are the possibilities to upgrade my existing Python installation (in my case from version 3.2.2 to 3.3.0) on my Windows 7 x64 system and not having to re-install all my packages? Is there a convenient/automated solution to do this? I'd like to end up with only one Python version on my system.
在我的 Windows 7 x64 系统上升级我现有的 Python 安装（在我的情况下从版本 3.2.2 到 3.3.0）并且不必重新安装我的所有软件包的可能性有哪些？有没有方便/自动化的解决方案来做到这一点？我想最终在我的系统上只有一个 Python 版本。

The problem is chiefly with packages written in C: they will be linked with the 3.2 Python code. It might just be a question of re-linking them, but I have had issues with popular packages like numpy(I currenty can't get that to compile on 3.3).
问题主要在于用 C 编写的包：它们将与 3.2 Python 代码链接。这可能只是重新链接它们的问题，但我遇到了流行包的问题，例如numpy（我目前无法在 3.3 上编译）。
The pure Python packages would probably be OK in theory, but honestly, is it worth taking the risk?
理论上，纯 Python 包可能没问题，但老实说，值得冒险吗？
It is safer to load the 3.3 versions of the packages, every time. Stick with 3.2 until you can upgrade everything. You can have more than one version of Python loaded on Windows, I have 2.6, 2.7, 3.2 and 3.3 co-existing. You just have to be careful with %PATH%, assoc, and ftype.
每次都加载 3.3 版本的软件包更安全。坚持使用 3.2，直到您可以升级所有内容。您可以在 Windows 上加载多个版本的 Python，我有 2.6、2.7、3.2 和 3.3 共存。你只需要小心 %PATH%、assoc 和 ftype。
