Python 为cvxopt构建控制盘失败-找不到vcvarsall.bat

我正在尝试用Python为work创建一个投资组合优化应用程序。所需模块之一是CVXOPT。当我尝试安装模块时，我得到一个错误，系统无法找到vcvarsall.bat。我发现有几个人遇到了同样的问题，我已经尝试了我在其他帖子中看到的所有解决方案。我安装了微软Visual C++最新版本，我升级了StudioToo工具…似乎没有任何效果。有人能提供一些见解吗？以下是我尝试运行命令“pip install cvxopt:”时命令行的输出：

Python库似乎有一个本机组件，需要使用VisualStudio构建工具进行编译

根据，对于Python 3.5（使用CPython），您需要安装for Visual Studio 2015

您需要检查Windows 8.1和Windows 10 SDK选项。再次尝试运行

pip安装时，

：

<>你必须从VisualC++的构建工具命令提示符（C:\Script文件（x86）\微软Visual C++ +构建工具）中运行命令，每次你都需要用Python编译。p>

如果您在windows上使用Python2.7，您将需要VS2008编译器—这是编译python本身的编译器，因此所有包都需要使用它。你应该从这里得到它：
