推荐答案

为自己省点心，从 本网站，您可以在其中找到许多适用于 Windows 的 Python 库的编译安装程序.如果您在 Windows 上使用 Python，我强烈建议您将此添加为书签.

Save yourself some grief and download it from this website where you'll find compiled installers for many Python libraries for Windows. I highly recommend bookmarking this if you are using Python on Windows.

确保为您使用的 Python 版本下载正确的版本.这些安装程序与官方 Python 安装程序(来自 python.org)一起使用，因为它们读取安装程序位置的注册表值并完成其余的工作.

Make sure you download the correct one for the version of Python you are using. These installers work with the official Python installer (from python.org), as they read the registry value for the installer location and do the rest of the magic.

由于这些是 Windows 安装程序包，只需双击并按照提示操作即可.

As these are Windows installer packages, just double click and follow the prompts.
