安装pysph时C++编译器可能出现的问题

Question

我在试着安装pysph。我尝试了MSVC 2017和MSVC 2022。当我尝试执行pip install时，最后会出现以下错误。

编辑:通过使用MSVC 2019和python 3.8修复(安装了早期版本的vtk用于mayavi)

我从未使用过PySPH，但以下是一些我想排除的东西：

1. 确保您使用的是正确的命令，应该是

​

pip install PySPH

​

这是取自https://pypi.org/project/PySPH/的

尝试从https://github.com/pypr/pysph安装

​

git clone https://bitbucket.org/pysph/pysph.git

​

请确保文档中有相关的依赖项，有一个专门用于安装https://pysph.readthedocs.io/en/1.0a1/installation.html#installing-the-dependencies-on-windows的 C++编译器部分。

您可以通过命令提示符检查是否安装了依赖项。

<name of dependency> --version

1. 一个可能的问题可能是测试失败https://github.com/pypr/pysph/actions/workflows/tests.yml，最近似乎已经修复了windows上的测试失败。我建议从最新版本的

安装git克隆。
