问题描述

这是一个超级用户的临界问题.我一直在使用pip install <x>从Windows 10上的powershell向我的3.6.2安装中添加软件包.我正在努力安装CVXPY.具体来说，我已经升级了setuptools并安装了Visual Studio c ++14.此外，我还按照github用户的建议安装了C ++ 2008: https://github.com/embotech/ecos/issues/53 .但是，我无法实现她的其他建议(edit ecosmodules.c)，因为我不认为该文件存在于我从github下载的原始包中

This is a borderline SuperUser question. I've been using pip install <x> to add packages to my 3.6.2 installation, from powershell on Windows 10. I'm struggling to install CVXPY. Specifically, I've already upgraded setuptools and installed visual studio c++ 14. Also, I installed C++ 2008 as suggested by a github user: https://github.com/embotech/ecos/issues/53. But, I couldn't implement her other suggestion (edit ecosmodules.c) because I dont think that file exists in the raw package I downloaded from github

以下是当我尝试通过pip install ecos安装密钥依赖项eCos时的回溯.

Below is the traceback when I try to install a key dependency, eCos, via pip install ecos.
