使用 Powershell 2.0 安装 ASP.net DNX

Question

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

问题是。当我运行这个时，我收到一条错误消息：

我可以只使用 Powershell 2.0 安装 DNX 还是必须升级到 3.0？

Answer 1

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该要求，但将其放在那里可能是有充分理由的。如果删除了要求，它真的可以工作，那将只是掷骰子。
