cvxpy/ecos pip 安裝錯誤

Question

這是一個邊緣超級用戶問題。 我一直在使用pip install <x>從 Windows 10 上的 powershell 向我的 3.6.2 安裝添加軟件包。我正在努力安裝 CVXPY。 具體來說，我已經升級了 setuptools 並安裝了 Visual Studio C++ 14。此外，我按照 github 用戶的建議安裝了 C++ 2008： https : //github.com/embotech/ecos/issues/53 。 但是，我無法實現她的其他建議（編輯 ecosmodules.c），因為我認為從 github 下載的原始包中不存在該文件

以下是我嘗試通過pip install ecos安裝關鍵依賴項 eCos 時的回溯。
