我正在尝试在 Windows 上安装 ASP.Net DNX。我按照以下说明操作：https ://github.com/aspnet/home#cmd

问题是。当我运行它时，我收到一条错误消息：

我可以仅使用 Powershell 2.0 安装 DNX，还是必须升级到 3.0？

The script 'dnvm.ps1' cannot be run because it contained a "#requires" statemen t at line 2 for Windows PowerShell version 3.0.

如果您想确保脚本能够正常工作，则必须使用 Powershell v3.0。当然可以修改脚本以删除要求，但它可能有充分的理由放在那里。如果取消该要求，它实际上会起作用，那将只是掷骰子。
