为 IronPython 安装 numpy

我想使用 c# 在 IronPython 中运行一些代码。在此代码中我需要使用 numpy。所以我尝试使用以下命令安装它：

 ipy -X:Frames -m pip install -U numpy

不幸的是，我收到一个错误和一条返回消息，告诉我安装不成功。错误信息如下：

Note: if you need reliable uninstall behavior, then install
with pip instead of using `setup.py install`:

  - `pip install .`       (from a git repo or downloaded source
                           release)
  - `pip install numpy`   (last NumPy release on PyPi)

我搜索了很多有关解决方案的信息，但我想这是一个非常常见的问题。 PS：我在许多其他软件包上也面临同样的问题。

有什么解决办法吗？

Python 首先是一种语言，并且在 C 语言中拥有默认实现：CPython。 IronPython 是该语言的另一种实现，基于 .NET。因此，它实现了默认的核心语言和大部分标准库。

通过 PIP 提供的一些 Python 包是纯 Python，并且依赖于 IronPython 支持的元素。然而，其他一些模块是特定于实现的。特别是，numpy 使用本机 C 代码，CPython 支持该代码，但 IronPython 不支持。有关 IronPython 问题跟踪器的更多信息：https://github.com/IronLanguages/ironpython2/issues/ https://github.com/IronLanguages/ironpython2/issues/

为了让它工作，numpy 必须提供与 .NET 的兼容性。我见过 numpy 的 .NET 重构，但从未让它工作。

您的问题的解决方案？避免混合 numpy 和 .NET。不过，如果你找到一种方法让它发挥作用，我很感兴趣。
