Python pip install cvxopt 错误：命令'C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\

Question

尝试使用" pip install＆quot"来安装cvxopt。使用窗口10，Python 3.6.4（64位），并且已经安装了Microsoft Build Tools 2015和Visual Studio 14.0。我还直接从PYPI下载了该模块，没有运气。需要这个以进行优化教程，所以有什么建议吗？这是命令行：

Answer 1

我们需要在cvxopt之前安装numpy mkl，请检查一下并下载numpy mkl软件包和适当的cvxopt，然后像以下内容一样安装它们：

1. 打开CMD和CD至下载文件夹

2. pip安装" numpy-1.13.1 mkl-cp36-cp36m-win_amd64.whl"

3. pip安装" cvxopt-1.1.9-cp36-cp36m-win_amd64.whl"

Answer 2

cvxopt由于某些重度依赖（Blas，Lapack，Suitesparse）而难以从源（尤其是在Windows上）安装。在您的情况下，它已经失败了，因为它具有一些兼容的C-Compiler设置的更简单的依赖性。

阅读您将看到的安装docs，二进制文件仅适用于Python 2.7和Python 3.4（在Windows上）！

因此，要么使用这些python versions之一，然后再次进行，或者使用anaconda-distripution，然后通过conda-forge安装，如上所述。我强烈推荐Anaconda-way！（编辑：在评论中提到的conda-forge中没有Windows-Builds）。

萨拉（Sara）基于Gohlke的二进制方法的方法可以起作用。但总的来说，这更麻烦（与其他库结合使用）。

还有官方的手册Windows安装，但恕我直言，这不值得（仍然限于某些python-versions）。
