Python - how can I change default path when installing modules?
提问by jonatr
I'm trying to install a Python Module by running a Windows installer (an EXE file). The Problem is that the default python folder and the defualt Installation Library are set To disc D:\ and are grayed out (meaning I can't change it). It might be fine is some places, but in my computer, D is the DVD drive, meaning that no installation is possible.
我正在尝试通过运行 Windows 安装程序（EXE 文件）来安装 Python 模块。问题是默认的 python 文件夹和默认的安装库设置为光盘 D:\ 并且显示为灰色（意味着我无法更改它）。有些地方可能没问题，但是在我的电脑中，D 是 DVD 驱动器，这意味着无法安装。
Is there any way to change this or to overcome this?

It's not "default folder", and there's a reason there's "found in registry" next to the version. You need to re-register the Python installation if you've moved it, either by installing it again (without removing) in the same folder, or changing the directory saved in registry (HKCU\Software\Python\PythonCore\X.X\InstallPath, possibly on Wow3264Node) either manually or using registration script.
它不是“默认文件夹”，并且版本旁边有“在注册表中找到”是有原因的。如果您移动了 Python 安装，则需要重新注册 Python 安装，方法是在同一文件夹中再次安装（不删除），或者手动或使用注册脚本更改注册表（HKCU\Software\Python\PythonCore\X.X\InstallPath，可能在Wow3264Node）中保存的目录。

Because what you're installing (you don't say what it is) seems to be standard distutils-generated installer (as Cat Plus Plus points out in his comment) you don't have to install it by running installer. You can install it using easy_install program what allows you to choose which Python to use. See my answer to Can I install Python windows packages into virtualenvs?question.
因为你正在安装的东西（你不说它是什么）似乎是标准的 distutils 生成的安装程序（正如 Cat Plus Plus 在他的评论中指出的那样），你不必通过运行 installer 来安装它。您可以使用 easy_install 程序安装它，该程序允许您选择要使用的 Python。请参阅我对Can I install Python windows packages into virtualenvs 的回答吗？题。

Now I see in your comment you're installing setuptools. This complicates things a little bit as this is the package which contains easy_install tool I mentioned above. You have chicken/egg problem here... There's solution for this, however. You can use ez_setupscript to install setuptools without using exe installer.
现在我在您的评论中看到您正在安装 setuptools。这使事情有点复杂，因为这是包含我上面提到的 easy_install 工具的包。您在这里遇到了鸡/蛋问题……但是，对此有解决方案。您可以使用ez_setup脚本来安装 setuptools，而无需使用 exe 安装程序。
