cvxpy/ecos pip安装错误
cvxpy/ecos pip installation error
这是一个临界超级用户问题。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，我无法实施她的其他建议（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。

我认为最好的 "solution" 是使用 windows linux 子系统。从这里，我能够使用 python3 -m pip install cmake 和 python3 -m pip install cvxpy
在 python 3.5 上安装 cvxpy 和所有依赖项
对于那些还没有安装 WLS 的人来说，这不是微不足道的，而是相对轻松的。
https://docs.microsoft.com/en-us/windows/wsl/install-win10
在基于 Anaconda 的 Win64 Python36 安装
conda install ecos
对我有用。
哪个允许 pip 安装 cvxpy。
如果你正在使用，我建议在 visual Studio 中安装所有 C++ 开发包。对我来说，下载最新的构建工具 from。
在详细信息部分检查 C++/CLI 支持。重新启动后，我可以 运行 pip install cvxpy 而不会出现错误。
这是一个临界超级用户问题。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，我无法实施她的其他建议（编辑 ecosmodules.c），因为我认为我从 github

我认为最好的 "solution" 是使用 windows linux 子系统。从这里，我能够使用 python3 -m pip install cmake 和 python3 -m pip install cvxpy
对于那些还没有安装 WLS 的人来说，这不是微不足道的，而是相对轻松的。 https://docs.microsoft.com/en-us/windows/wsl/install-win10
在基于 Anaconda 的 Win64 Python36 安装
conda install ecos
对我有用。
哪个允许 pip 安装 cvxpy。
如果你正在使用，我建议在 visual Studio 中安装所有 C++ 开发包。对我来说，下载最新的构建工具 from。
在详细信息部分检查 C++/CLI 支持。重新启动后，我可以 运行 pip install cvxpy 而不会出现错误。
