有什么帮助吗?

推荐答案

UPDATE正如有人在编辑中指出的那样，如果您只下载 vc_redist.x64.exe，它只有 15MB，为此请转到其他工具和框架"并选择 MS Visual C++

UPDATE As some one pointed out in the edit, if you download only the vc_redist.x64.exe it's just 15MB, for that go to "other tools and frameworks" and choose MS Visual C++

通过从这里安装工具解决了问题

问题是一些 python 模块需要 C++ 工具来编译，因为它们是用 C++ 编写的.

the thing is that some python modules require C++ tools to compile with a python wrapper around, as they are written in C++.

下载安装程序后，您可以选择特定工具或下载提供的其他工具.

once the setup is downloaded you can select the specific tools or download other facilities provided.

它大约有 4 GB，但如果将来您需要使用其他一些用 C++ 制作的模块，就可以解决这个问题.

it's somewhere around 4 GB but solves the purpose if in future you need to use some other module which are made in C++.
