Question

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。因此，我尝试使用以下命令进行安装：

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

不幸的是，我收到一个错误，并返回一条消息，告诉我这是安装失败。错误消息如下：

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普遍的问题。附：我在其他许多软件包中也遇到了同样的问题。

有什么解决方案？

Answer 1

Python首先是一种语言，并且在C：CPython中具有默认实现。 IronPython是基于.NET的另一种语言实现。因此，它实现了默认的核心语言和大多数标准库。

某些可通过PIP获得的Python软件包是纯Python，并且依赖于IronPython支持的元素。但是，其他一些模块特定于实现。特别地，numpy使用本机C代码，CPython支持此代码，但IronPython不支持。有关IronPython问题跟踪器的更多信息：https://github.com/IronLanguages/ironpython2/issues/

要使其工作，numpy必须提供与.NET的兼容性。我已经看到了numpy的.NET重构，但从未成功。

您的问题的解决方案？避免将numpy和.NET混合使用。不过，如果您找到一种使它起作用的方法，我会很感兴趣。
