note: This error originates from a subprocess, and is likely not a problem with pip.

我看过了网上的说法，没用
已安装boost和cmake
有人可以教教我怎么办吗？
需要安装Visual Studio C++
You must use Visual Studio to build a python extension on windows. If you
are getting this error it means you have not installed Visual C++. Note
that there are many flavors of Visual Studio, like Visual Studio for C#
development. You need to install Visual Studio for C++.
