Why do some Python packages require Visual Studio?

使用C语言编写的CPython扩展模块的源代码安装需要C编译器. Visual Studio提供了一种这样的编译器.

Installation from source of CPython extension modules written in C requires a C compiler. Visual Studio provides one such compiler.

为避免这种情况，请使用这些之类的二进制安装程序.

To avoid it, use binary installers such as these.

此外，由于许可限制，扩展模块可能不会自动安装某些dll，而您必须安装手动提供这些dll的Visual Studio.

Also, due to licensing restrictions, an extension module may not install some dlls automatically and you have to install Visual Studio that provides these dlls manually.
