python - IronPython 2.7.8 与 pip

问题描述

在 Windows 10 上安装 IronPython 2.7.8（最新稳定版本）后，我尝试运行 pip，但出现如下错误：

PS C:\Program Files\IronPython 2.7> ipy.exe -m pip install numpy
Unhandled exception:

IndexError: index out of range: -1

我不知道如何解决这个错误。似乎是 IronPython 的问题？我无法将软件包安装到 IronPython，因此无法进行任何开发。任何人都可以帮忙吗？
