如何在 python 中构建 C++ 程序？

Question

我正在使用 Anaconda。我想从 github 构建一个源代码： https://github.com/mmolero/pypoisson

当我在终端中使用以下命令时，会出现以下错误： 命令：python setup.py build

错误：

不仅对于此源代码，而且对于其他代码都无法构建。 需要注意的是，我在我的PC中安装了visual 2015、visual 2017、GCC编译器。操作系统为 Windows 10。

不同的源代码需要不同类型的编译器，我该如何解决这个问题？

Answer 1

该输出的关键部分是fatal error C1189: #error: OpenMP is required。猜测一下，我会说这意味着您需要有可用的 OpenMP，而您不需要。有another SO thread on installing OpenMP on Windows，其中包括一些pretty recent answers。
