"Python version 2.7 required, which was not found in the registry" error when attempting to install netCDF4 on Windows 8
提问by bogdan
I use Anaconda 1.7, 32 bit. I downloaded the correct version of the netCDF4 installer from here.
我使用 Anaconda 1.7，32 位。我从这里下载了正确版本的 netCDF4 安装程序。
I attempted to copy the HKEY_LOCAL_MACHINE\SOFTWARE\Python folder into HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node. No luck.
我试图将 HKEY_LOCAL_MACHINE\SOFTWARE\Python 文件夹复制到 HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node 中。没运气。
Does anyone have any idea why this might be happening? Anaconda installed in the default location, C:/.
有谁知道为什么会发生这种情况？Anaconda 安装在默认位置，C:/。
Yes, I know Anaconda has netCDF4 in the packages list - but if you look closely, it's only offered for Mac and Linux.
是的，我知道 Anaconda 在包列表中有 netCDF4 - 但如果你仔细观察，它只提供给 Mac 和 Linux。

Just download Python 2.7.6 Windows Installerfrom the official Python download page, and launch the install package.
只要下载的Python 2.7.6的Windows安装程序从Python的官方下载页面，并启动安装包。

I had such problem. Solution was simple :
我有这样的问题。解决方案很简单：
- Install python 2.7 64bit version.
- Export HKEY_LOCAL_MACHINE\SOFTWARE\Python.
- Remove Python 2.7.
- insert exported reg file.
- rename all C:\Python27 to C:\Anaconda ( insert your path ).
- 安装python 2.7 64位版本。
- 导出 HKEY_LOCAL_MACHINE\SOFTWARE\Python。
- 删除 Python 2.7。
- 插入导出的reg文件。
- 将所有 C:\Python27 重命名为 C:\Anaconda（插入您的路径）。
P.S. Sorry, for bad grammar.
PS对不起，语法不好。

This error can occur if you are installing a package with a different bitness than your Python version. To see whether your Python installation is 32- or 64-bit, see here.
如果您安装的包的位数与 Python 版本不同，则可能会发生此错误。要查看您的 Python 安装是 32 位还是 64 位，请参见此处。
Some superpacks (e.g. for Scipy) available on SourceForge or python.org are for 32-bit systems and some are for 64-bit systems. See this answer. In Windows, uninstalling the 32-bit and installing the 64-bit version (or vice versa if your installation is 32-bit) can solve the problem.
SourceForge 或 python.org 上提供的一些超级包（例如用于 Scipy）适用于 32 位系统，有些适用于 64 位系统。看到这个答案。在 Windows 中，卸载 32 位并安装 64 位版本（如果您安装的是 32 位，则反之亦然）可以解决问题。

I had the same issue when using an .exe to install a Python package (because I use Anaconda and it didn't add Python to the registry). I fixed the problem by running this script:
我在使用 .exe 安装 Python 包时遇到了同样的问题（因为我使用 Anaconda 并且它没有将 Python 添加到注册表中）。我通过运行这个脚本解决了这个问题：

I think it really depends on why this error is given. It may be the bitness issue, but it may also be because of a deinstaller bugthat leaves registry entries behind.
我认为这真的取决于为什么会出现这个错误。这可能是位数问题，但也可能是由于卸载程序错误导致注册表项落后。
I just had this case because I need two versions of Python on my system. When I tried to install SCons (using Python2), the .msi installer failed, saying it only found Python3 in the registry. So I uninstalled it, with the result that no Python was found at all. Frustrating! (workaround: install SCons with pip install --egg --upgrade scons)
我刚刚遇到了这个案例，因为我的系统上需要两个版本的 Python。当我尝试安装 SCons（使用 Python2）时，.msi 安装程序失败，说它只在注册表中找到 Python3。所以我卸载了它，结果根本找不到Python。令人沮丧！（解决方法：使用 安装 SCons pip install --egg --upgrade scons）
Anyway, I'm sure there are threads on that phenomenon. I just thought it would fit here because this was one of my top search results.
无论如何，我确信有关于这种现象的线索。我只是认为它适合这里，因为这是我的热门搜索结果之一。

Check for the 32/64 bit you trying to install. both python interpreter and your app which trying to use python might be of different bit.
检查您尝试安装的 32/64 位。python解释器和您尝试使用python的应用程序可能有所不同。
