python - cvxpy/ecos pip安装报错

Question

这是一个边界 super 用户问题。我一直在使用 pip install <x>从 Windows 10 上的 powershell 将软件包添加到我的 3.6.2 安装中。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。另外，我按照 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(编辑 ecosmodules.c)，因为我认为我从 github 下载的原始包中不存在该文件

以下是我尝试通过 pip install ecos 安装关键依赖项 eCos 时的回溯.
